> In particular, it would be good to implement more of the XPath grammar.
> However, once we get into the realm of more complex paths there becomes a
> question about optimisation of XPath selection. If the documents are
> pre-parsed, then XPath query elements can be rewritten as SQL queries and
> you get the optimisation of the planner on your side.

> it delivers a very simple interface to the user and is (code-wise) also
> very straightforward. Maybe less efficient queries are a penalty worth paying?
