Description Henri Sivonen 2008-08-28 12:02:09 UTC 
The spec should define script execution for XHTML5. It would be good to use the same definition for running SVG scripts in both XHTML5 and HTML5.

Based on the demo http://hsivonen.iki.fi/test/moz/script-execution.xhtml , I suggest the following, which seems to be what Gecko and WebKit do with both XHTML and SVG scripts:
 1) When the DOM builder gets a start element event, append element node. Don't run script yet.
 2) When the DOM builder gets a characters event, append characters to the current node.
 3) When the DOM builder gets an end element event, pop. If the popped element was 'script' in the http://www.w3.org/1999/xhtml or http://www.w3.org/2000/svg namespaces, run the concatenation of child text nodes as script.

Note: Opera runs the concatenation of child descendant nodes instead, which makes text that is descendant of more than one script element run many times.
Comment 1 Ian 'Hixie' Hickson 2008-12-29 23:21:09 UTC 
The spec says:

# When an XML parser creates a script element, it must be marked as being "parser-inserted".
# When the element's end tag is parsed, the user agent must run the script element.

I can't define what the processing model for SVG should be, that would need to be in the SVG spec.
