Thank you!

Fixed in the next paragraph already--presumably in response to similar  
feedback from gsnedders.

On the topic of foreignObject: Shouldn't HTML5 actually *disallow*  
<html> as a child of <foreignObject> and make the content model of  
foreignObject equivalent to the content model of <body>? The commented  
out SVG-in-text/html functionality doesn't support <html> as a child  
of <foreignObject>.

It's OK for the multiple ID issue. However, this sentence is known to  
be confusing: "The value must be unique in the subtree within which  
the element finds itself and must contain at least one character." It  
should say that the ID must be unique within all nodes that are  
inserted into a document, a document fragment or an interconnected set  
of nodes that live outside a document or document fragment.

(I think I should remove xml:id support from Validator.nu anyway.)

I'd like to withdraw my suggestion to predefine Dublin Core. DC  
metadata in HTML is worse than useless: Some DC metadata elements  
duplicate HTML and HTTP information but as "invisible" metadata and  
the others are too vaguely defined to be useful on the Web scale.

Yes, except the advice "The i element should be used as a last resort  
when no other element is more appropriate. In particular, citations  
should use the cite element, defining instances of terms should use  
the dfn  element, stress emphasis should use the em  element" may not  
be respectful of the authors' time in the absence of concrete benefits  
for justifying the advice (other than future potential for  
unconventional styling).
