Package com.saxonica.functions.extfn
The package com.saxonica.functions.extfn contains implementations of extension
functions in the Saxon namespace.
It also contains the class VendorFunctionSetPE which acts as a factory class for
generating instances of these extension functions.
These extension functions are implemented using a variety of mechanisms. Some are implemented in the same way as system functions. Some use the "integrated extension function" mechanism introduced in Saxon 9.2.

saxon:object-map(), which converts an external object to a mapParse This class implements the saxon:parse() extension function, which is specially-recognized by the system because it needs access to parts of the static contextParseHtml Supports the saxon:parse-html() function, a variant of saxon:parse() that differs only in that it uses the TagSoup HTML parserParseXPath This class implements the saxon:parse-XPath() extension function, which is specially-recognized by the system because it needs access to parts of the static contextPedigreeFn The saxon:pedigree function, new in Saxon
