I agree 100%. By avoiding namespaces in the text/html serialization of  
HTML5 we are creating unnecessary complications fro authors and  
implementors. IE already has a namespace implementation somewhat  
compatible with XMl namespaces for the text/html serialization and all  
major browsers have XML namespace implementations that could be reused  
for the text/html serialization. Authors already familiar with XML  
namespaces and IE namespaces will find transitioning to HTML5 text/ 
html SVG MathML etc needlessly non-standard (in the sense that it is a  
complete diversion to what they're used to).

HTML5 should include namespaces in either serialization that are  
consistent with XML namespaces and IEs text/html namespaces.

Take care,
