I'm not so sure. PassiveTeX can recognize MathML markup in XSL-FO. 
FOP can recognize SVG in XSL-FO. It's entirely possible we may one 
day have a processor that recognizes all three at once. XSL-FO really 
doesn't cover the presentational range that SVG and MathML do. A 
document that includes text, pictures, and equations really needs all 

MathML has two vocabularies: presentation and content. Only the 
presentation half is well supported by current software. SVG is 
really nothing but presentation, even more than XSL-FO. For example, 
a table of numbers is much more repurposible than an SVG picture that 
shows a pire chart or a line graph of the numbers.

XHTML tables probably wouldn't be included, both because XSL-FO has 
its own tables syntax and because XSL-FO and HTML serve the same 
purpose: formatting text for presentation to a human reader. You'd 
pick one or the other but not both.

I do not think XSL-FO is any more or less semantic than HTML. It is 
more complex and more powerful; but there's no true semantic 
difference between a fo:block and an HTML div or a fo:table and HTML 
table. The same arguments being made for deprecating XSL-FO on the 
Web equally well apply to HTML. I think that's a non-starter.
