Note that this is similar to IE's "XML islands" with the <xml> elementIt's believed that there are some conflicts with the <xml> element itself, since it creates a separate document that is tied to the <xml> element in the DOM.

Latest revision as of 16:07, 10 November 2012

This document is obsolete.

For the current specification, see: HTML Standard: SVG


Please put ideas for what it should look like here.

Each example should have a green circle, with an embedded HTML table, and should say how to handle tokeniser errors and tree construction errors.

Hardcoded element names

 <p>
   Hello world.
   <svg viewbox="0 0 10 10">
     <circle x=5 y=5 r=5 stroke=green>
     <foreignObject> <table><tr><td>1<td>2<tr><td>3<td>4</table> </foreignObject>
   </svg>
 </p>

Tokeniser recovers from errors by ignoring them and moving on.

Tree construction recovers from errors by closing the <svg> element.

Extensibility Element (<ext>)

Moved to Extensions, since this is a potentially generic mechanism.

Make sure to test your proposals... :-)

<svg> as document element

This is not a syntax proposal but I'd like to able to have SVG graphics in text/html without the need to wrap it inside HTML and without having implied <html>, <body>, etc. (I being Anne.)

Rationale:

  • It's often easier to generate text/html documents than other types of documents (Live DOM Viewer, PHP)
  • It allows you to use text/html-style syntax for SVG graphics which makes authoring easy.
  • It makes creating graphics that use features from HTML and MathML easier.
<svg viewbox="0 0 10 10">
  <circle x=5 y=5 r=5 fill=lime>
  <foreignObject> <table><tr><td>1<td>2<tr><td>3<td>4</table> </foreignOBJECT>
</svG>

It's not clear that authoring would be easier with looser error handling, and introduces the incompatibilities mentioned above. A safer approach would be to first introduce the more conservative syntax, then observe how it is used and specify from real-world use cases incrementally. It's also not clear how this is to be distinguished from SVG content with embedded HTML (MIME Type?). -Shepazu
