1.  Introduction

   Scalable Vector Graphics (SVG) is a standard that defines vector-
   based graphics for the web, graphics that can be expressed in XML
   format.  SVG is an extensible format, with support for various
   metadata elements and animation.  In some cases, it is preferable to
   have an SVG profile that is targeted at smaller platforms, and/or to
   have security in mind.  This document defines a profile of SVG for
   such use cases, called the SVG Tiny PS profile, that limits the
   allowed elements to a subset of the features supported by the overall
   SVG specification.

   The SVG standard is defined by the World Wide Web Consortium (W3C)
   and the current version is 1.1 [SVG].  The W3C also defines a
   simplified profile of SVG published as SVG Tiny [SVGT], with the
   current version at 1.2.  This document defines the SVG Tiny PS
   profile in the terms of the simplified SVG Tiny 1.2 as the base.  The
   SVG Tiny PS profile identifies elements that are required,
   disallowed, or otherwise allowed from the set of elements defined by
   SVG Tiny 1.2.  No elements are added to SVG Tiny PS, and any elements
   not explicitly mentioned in this document follow the guidance
   provided by SVG Tiny 1.2.

2.  SVG Tiny PS Profile

   This document defines the SVG Tiny PS profile in the terms of the
   simplified SVG Tiny 1.2 as the base.  The following sections
   reference sections within the SVG Tiny PS profile that are required,
   disallowed, or otherwise allowed from the set of elements defined by
   SVG Tiny 1.2.  No elements are added to SVG Tiny PS that are not
   found within SVG 1.1 or SVG Tiny 1.2, and any elements not explicitly
   mentioned in this document follow the guidance provided by SVG Tiny
   1.2.

2.1.  Specific Instructions for the SVG Tiny PS Documents

   The elements and attributes below are required within the root <svg>
   element of an SVG Tiny PS document.

   *  Document Definition: The SVG Tiny PS document MUST be defined as
      described in SVG Tiny 1.2 Section 1.3.  This includes setting the
      following attributes as follows:

   xmlns="http://www.w3.org/2000/svg"
   version="1.2"
   baseProfile="tiny-ps"

   [ Note to WG: Based on other baseProfile, this should be the minimum
   profile required to render the image.  Tiny PS should be a subset,
   but we're unsure if we should create a smaller profile. ]

   *  title: The <title> element MUST be present and its contents MUST
      NOT be empty.  The title element MUST occur only once as a sub-
      element of the svg element.  The contents SHOULD be no more 64
      characters.

   *  desc: The <desc> element MAY be present with a longer description.
      If present, its contents MUST NOT be empty, and care SHOULD be
      given to minimize the file size of the document.

2.2.  Permitted Sections with Restrictions

   The following sections from SVG Tiny 1.2 MAY be used within an SVG
   Tiny PS document with the further restrictions as noted.

   *  Section 8: Paths - This section defines methods used for defining
      vector-based paths that can be rendered.  The attributes "d" and
      "pathLength" MUST NOT be animated.  The elements described within
      "8.2.1 Animating path data" MUST NOT be present within an SVG Tiny
      PS document.

RFC draft-svg-tiny-ps-abrotman-SVG-TINY-PS                    April 2023

   *  Section 9: Basic Shapes - This section defines primitives that can
      be used to render basic shapes.  The attributes "x", "y", "width",
      "height", "rx", and "ry" MUST NOT be animated.

   *  Section 10: Text - This sections describes the methods for
      defining text that should be rendered similar to any vector-based
      graphic elements.  The "editable" attribute SHOULD NOT be present
      in an SVG Tiny PS document, if it is, it MUST be set to "none".
      The attributes "x", "y", and "rotate" MUST NOT be animated.

   *  Section 11: Painting - This section describes the methods used to
      render the paths ("stroked") and shapes ("filled") visible.  Any
      of the attributes described MUST NOT be animated within an SVG
      Tiny PS document.

2.3.  Disallowed Sections, Elements, and Attributes

   The elements and attributes described in the sections below MUST NOT
   be present in an SVG Tiny PS document:

   *  Section 5.7: The 'image' Element - This section defines methods
      for displaying a raster image within the context of an SVG image.

   *  Section 5.8.2: The 'switch' Element - This section defines methods
      for conditional processing of the document.

   *  Section 12: Multimedia - This section describes the elements that
      augment an image with audio or video.

   *  Section 13: Interactivity - This section describes elements
      related to user actions and responsiveness to those events.

   *  Section 14: Linking - This section describes links to internal and
      external end points.

   *  Section 15: Scripting - This section describes methods for adding
      executable content.

   *  Section 16: Animation - This section describes methods for
      transforming or otherwise animating elements over time.

   The attributes below are specifically called out from the sections
   above due to their widespread use.  For a more complete list, refer
   to the full content in the sections above.

   *  zoomAndPan: The "zoomAndPan" attribute SHOULD NOT be present in an
      SVG Tiny PS document.  If it is present, it MUST be set to
      "disable".

RFC draft-svg-tiny-ps-abrotman-SVG-TINY-PS                    April 2023

   *  externalResourcesRequired: The "externalResourcesRequired"
      attribute SHOULD NOT be present in an SVG Tiny PS document.  If it
      is present, it MUST be set to "false".

   *  focusable: The "focusable" attribute SHOULD NOT be used within an
      SVG Tiny PS document.  If it is present, it MUST be set to
      "false".

   *  snapshotTime: The "snapshotTime" attribute SHOULD NOT be used
      within an SVG Tiny PS document.  If it is present, it MUST be set
      to "none".

   *  playbackOrder: The "playbackOrder" attribute SHOULD NOT be used
      within an SVG Tiny PS document.  If it is present, it MUST be set
      to "all".

   *  timelineBegin: The "timelineBegin" attribute SHOULD NOT be used
      within an SVG Tiny PS document.  If it is present, it MUST be set
      to "onLoad".

2.4.  Additional Considerations for Creating SVG Tiny PS Documents

   The following are special considerations that SHOULD be taken when
   creating an SVG Tiny PS document:

   *  The file size of SVG Tiny PS documents SHOULD be as small as
      possible, and SHOULD NOT exceed 32 kilobytes.  That size should be
      evaluated when the document is uncompressed.

   *  An SVG Tiny PS document MUST include at least two colors when
      rendered.

   *  Section 17: Fonts - This sections describes the methods for
      defining specific characters to be used within an SVG document.
      Embedded character definitions MAY be used in an SVG Tiny PS
      document, but the document SHOULD only include the characters to
      be rendered, and SHOULD NOT include any additional characters that
      are not to be rendered.

   *  Section 18: Metadata - This section summarizes standard methods
      for including structured data about the content within an SVG
      document.  While metadata can support utility and accessibility
      and MAY be included in an SVG Tiny PS document, careful
      consideration SHOULD be given to how the metadata element and
      extensible metadata attributes are used to avoid increasing the
      file size of the document.

Brotman & Adams          Expires 9 October 2023                 [Page 5]
RFC draft-svg-tiny-ps-abrotman-SVG-TINY-PS                    April 2023

   *  An SVG Tiny PS document MAY include transparent elements, however
      care SHOULD be taken to understand the implications of
      transparency when rendered.  Given that the author has no control
      over how the logo is ultimately displayed, transparency to the
      underlying display mechanism could result in undesirable effects.

3.  Security Considerations

   Many of the requirements imposed by the SVG Tiny PS profile are
   designed to minimize potential security concerns introduced by
   interactive content into a user experience not typically designed to
   handle it.  Every consideration has been made to reduce the scope of
   SVG images to the minimum elements necessary to render locally
   defined, static vector graphics.

3.1.  Portability

   The SVG documents meant to be used with this profile should be fairly
   portable, and should likely be self-contained.  The document authors
   cannot be certain that the client will have an active network
   connection.
