Yes.

It isn't (see a post from earlier today on this same subject).

Short answer: It isn't.

Longer answer: There is a method in the QuickFIX Message class to
"render" it as XML based on an XML Data Dictionary.  However, the tag
names in FIXML diverge from those in the FIX spec (why, in the name of
all that is holy did they do that?) so the output generated using the
default Data Dictionary files is not FIXML.  I suspect you could whip
up a Data Dictionary that used the FIXML names and be able to generate
mostly FIXML-compliant messages.  But I'm sure there will be other
gotchas (e.g. should attributes be used, or nested text elements) that
come up.
