The first other factor that comes to my mind is:  why does the
organization want to convert the legacy data format into XML?

Are there particular problems in the existing setup that need to be
solved?  Threats to the existing data or software?  Are there particular
opportunities in the XML space the organization wants to exploit?  Or is
it just a desire for buzzword compliance?

A second factor that comes to mind is: in my experience, organizations
seldom have emotions, but people working in them often do.  Is it the
organization's management who want to move to XML?  Or the domain
experts?

Some.

And some.

XML is easy enough to learn that lots of people have learned it, and
lots of those people have learned it by designing XML vocabularies and
building XML applications.  So your candidate #1 has a reasonable chance
of success.

XML is used in enough different contexts that anyone who works with XML
for a living has probably acquired a fair amount of experience learning
enough about a domain to communicate with domain experts and work with
them to design a suitable vocabulary and workflow.  So your candidate #2
also has a reasonable chance of success.

In an organization full of domain experts who don't know anything about
markup, it may be easier for an XML expert to learn the domain
sufficiently than for a domain expert to learn about XML. 

Good luck.
