Class VendorFunctionSetHE.HasLocalNamespaces

  • All Implemented Interfaces:
    Callable, Function, GroundedValue, Item, Sequence
    Enclosing class:

    public static class VendorFunctionSetHE.HasLocalNamespaces
    extends SystemFunction
    Implement saxon:has-local-namespaces. The function takes an element node as input and returns true if (a) the element is parentless, or (b) the parent is a document node, or (c) the element has namespace declarations or undeclarations that differ from those of the parent element (that is, if its in-scope namespace bindings are different from those of the parent element).

    This function is provided for use by the XSLT-compiler-in-XSLT, so that it can decide efficiently whether to generate an "ns" element containing namespace bindings in the SEF file.
