A promising approach is described in "Persistent DOM: An
architecture for XML repositories in relational databases"
by Richard Edwards and Sian Hope:

http://www.sees.bangor.ac.uk/~rich/research/papers/uwb_rge_IDEAL2000.pdf

This paper describes a relational schema that can
store any kind of XML structure.  Although they don't
mention this in the paper, the schema also allows
for efficient implementations of queries along all the
XPath axes, so it would probably be a good foundation for
implementing XQuery.
