Good approach!

May be Kornel had a solution to several problems at once: replace @doc 
with @body ?

I meant by validators. And in that regard: You and Boris discussed the 
similarity with data URIs. And it was said that quotes inside @doc 
would have to be escaped. But what kind of escaping? Would it be the 
same kind of escape as in data URIs -  that is (I suppose) percentage 
escaping? Would it be another kind of escape - like character 
references/entities?  I suppose it should be enough to use single 
quotes if @doc itself uses double quotes? <iframe doc=" <element 
attr='value'></element> " > ? And a third kind of "escape" would be to 
not use quotes, when the text/html serialisation permits that ...
