        Let's describe a bit more closely what is built. First the xsltStylesheet structure holds a pointer to the template hash table.

Predicate expressions are not compiled at this stage, they may be at run-time if needed, but in this case they are compiled as full XPath expressions (the use of some fixed predicate can probably be optimized, they are not yet).
