Appendix O: Feature Strings

Contents

• O.1 Introduction
• O.2 SVG 1.1 feature strings
• O.3 SVG 1.0 feature strings

This appendix is normative.

O.1 Introduction

The following are the feature strings for the 'requiredFeatures' attribute. These same feature strings apply to the hasFeature method call that is part of the SVG DOM's support for the DOMImplementation interface defined in DOM Level 2 Core [DOM2-CORE] (see Feature strings for the hasFeature method call). In some cases the feature strings map directly to SVG modules, a set of attributes, properties or elements, in others they represent some functionality of the User Agent user agent (that it is a dynamic viewer for example). Note that the format and naming for feature strings changed from SVG 1.0 [SVG10] to SVG 1.1. The SVG 1.0 feature strings are listed below after the SVG 1.1 feature strings and User Agents should support all listed feature strings for compatibility reasons. However, the SVG 1.0 feature strings can be considered deprecated.

O.2 SVG 1.1 feature strings

(Because the feature string "http://www.w3.org/TR/SVG11/feature#SVG" can be ambiguous in some circumstances, it is recommended that more specific feature strings be used.)
