Right, it's not allowed in <map> in XHTML 1.1.

In terms of what browsers do, yes. In the XHTML 1.1 approach, the id 
attribute (which is obligatory for <map> in XHTML 1.1) is supposed
be used for establishing the connection. You are also supposed to use
a usemap attribute with an identifier value (usemap="foo", not 
usemap="#foo"), which isn't supported by browsers.

Stop using XHTML 1.1 and move to XHTML 1.0 or, better still, HTML 4.01.

Remember that XHTML 1.1 is an exercise in futility. It's just a 
theoretical construction that tries to XMLify HTML according to the
"modular approach", as opposite to the monolithic approach of XHTML 4.01
(and, rather randomly, makes some undocumented or poorly documented 
changes here and there and throws in the Ruby module). It's a dead end, 
and people using it have just been misled by the idea of "using the latest

Well, why not? Your document would be invalid, but how important would it 
be to use valid XHTML 1.1 on web pages when browsers don't support XHTML 
1.1 anyway? If you use general XML tools for processing your documents 
(the only rational reason for using XHTML these days), then you might run 
into problems _if_ those tools use validating parsers _and_ do not 
tolerate validation errors.
