They fit quite nicely if the HTML parser reports an equivalent XHTML  
document to the schema layer, which is what my parser does. Jing  
doesn't care what calls the ContentHandler methods.

Parsing text/html from the real Web using an XML parser is an  
exercise in futility. Therefore, a real-world-compatible parsing  
algorithm is needed. With that in place, there's no good reason for  
text/html suppliers to make their stuff XML. And having people  
pretend that they are sending XML when they aren't wouldn't do any  
good to XML.
