This is very strange, Given that an & should generate a parse error, and
& should (and does) work, why do you not trust that & will work,
but you trust that all agents will not generate an error on the incorrect
markup???

It's basically not possible to produce an unquoted & in an attribute
value in either the html or xml output methods from xslt (as neither XML
nor HTML allow this)
