Metacat

We don't fully support XPath syntax. Maybe we need this feature as well, but its lower prioroty than other bugs and features.

XPath syntax has been extended to allow predicates with the following limitations:

• if using a comparison, xpath expression must come before the equal sign and a string literal after (the predicate may contian an xpath expression by itself)
• '=' is the only comparison supported.
• no function calls in predicates
• supports multiple predicates, but not nested predicates

If any more enhancements are needed so that metacat comes closer to supporting the full XPath syntax, switching to an XQuery database should be considered.
