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.
