Due to the lack of support of XdmFunctionItem objects in Saxon/C it should be possible to execute in XQuery to string a map object but this fails.

The following python script supplied by the user we add to our unit tests for investigation purposes:

import saxonc

with saxonc.PySaxonProcessor(license=False) as proc:
    print(proc.version)

    xquery_processor = proc.new_xquery_processor()

    query = """declare namespace output = "http://www.w3.org/2010/xslt-xquery-serialization";

declare option output:method 'json';

map { 'prop1' : 'value 1', 'prop2' : 'value 2' }"""

    xquery_processor.set_property("!method", "json")

    result = xquery_processor.run_query_to_string(query_text = query)

    print("string result: ", result)

    result = xquery_processor.run_query_to_value(query_text = query)

    print("value result: ", result)

Outputs:

Saxon/C 1.2.1 running with Saxon-HE 9.9.1.5J from Saxonica
string result:  None
value result:  None

The equivalent works fine in XSLT. When returning a value object this should in fact not be possible. An error message should be reported to the user stating that "FunctionItem found. Currently not be handled"
