Built-in extensions
Nearly all the extension functions provided in the Java product in the saxon
namespace are available.
The exceptions are:
saxon:key-map
saxon:last-modified
saxon:parse-dateTime
saxon:send-mail
saxon:object-map
saxon:unparsed-entities
It is possible to wrap an external C# object in an XdmExternalObject. However, the external object lookup expression (a Saxon extension) is not available.
