Absolutely. I'm not a member of the WG and I found no definitive answer 
in the spec.

Yes. Which I read as: "this section contains examples describing how 
the currently available solutions mostly operate".

Well, sure. It rather depends on the purpose of a specification though, 
doesn't it.
Does one write a specification to codify existing practice and promote 
interoperability, or does one write a specification that aims at the 
clear blue sky and tries to specify the next generation of technology: 
to lead the implementors?

Most specifications are a mixture of both but I think history shows the 
truly effective ones have been biased towards codifying what is already 
a de facto standard. In other words, the working group can write 
whatever they like into the spec, but if the vendors consider it 
unreasonably difficult to do they'll just ignore it and produce a 
partial implementation.

This has been an endemic problem with W3 standards (examples abound: 
HTML 4, CSS 2, XHTML) and I think the newish CR process where features 
are removed from the spec if they're not implemented by at least 2 
independent parties is a good reaction.

Having said that, I don't think its unreasonable to expect the built in 
lexicons for English language synths to handle cafe and café 
adequately, but I'm not sure simply writing this in the specification 
would have any effect. You'd really need to test then lobby any vendors 
who aren't doing the right thing.
