SVG Tiny Portable/Secure
draft-svg-tiny-ps-abrotman-00
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
