You're missing the point.

The hype of XML is that you can modify what's in the document
structure; it's got all sorts of good, crunchy metadata so that that
should work out very nicely.

Reality is that it's as fragile as any other sort of system, and
perhaps moreso.  

If you change the hierarchy of the database, all the code written for
the old hierarchy will have to change to reflect the new hierarchy.

_Some_ changes won't require code changes; adding a field (aka slot
aka frame aka element) may not require any coding changes, if it has
no crucial semantic effect.

But changes in hierarchy likely strike down the house of cards.

The point isn't of whether you can create a query; it's of whether you
can create a query that will still work after you reorder the fields
or move a field to a different level of the ODBMS hierarchy.

The issues aren't all that different from using relational databases,
except that with relational databases, you don't normally get forced
into writing code involving specific database navigation strategies.
