Update: I'm working on that too: 

Jonathan: I will echo what Henri says.  Except for edge cases, HTML5 
parsers and serializers can simply be considered a 'drop in' replacement 
for XML parsers and serializers.  Every effort has been made to ensure 
that the edge cases are as small as possible.  And the cases where the 
differences are unavoidable are clearly documented.  Apparently Henri's 
favorite example is form feed characters.  Mine is consecutive dashes in
