This document is obsolete.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
