Abstract

   This document specifies SVG Tiny Portable/Secure (SVG Tiny PS) -- A
   Scalable Vector Graphics (SVG) profile to be used with documents that
   are intended for use with more secure requirements, and in some
   cases, in conjunction with a limited rendering engine.

1.  Introduction

   In some cases, it may be preferable to have an SVG profile that is
   targetted at smaller platforms, or have security in mind.  These
   documents are meant to be self-contained and scalable.  SVG allows
   some elements that can create usability and scalability challenges
   within the constrained of those use cases.  This document defines a
   profile of SVG for those use cases, effectively limiting the allowed
   elements to a subset of features supported by the overall SVG
   specification.

   The SVG standard is denied 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
