Struct XPath10Catalog 

pub struct XPath10Catalog;

Catalog that restricts available functions to the XPath 1.0 core set.

For empty-namespace lookups (XPath 1.0 mode), only the 27 core functions are allowed, and they are resolved via FUNCTION_REGISTRY using FN_NAMESPACE. For non-empty namespace lookups, delegates to BuiltinCatalog unchanged.
