set-up-double-metaphone does not generate dictionary

[mthahir]

The generated dictionary is empty.
After reviewing the code on algorithms:setup-double-metaphone, I noticed that line#81 has single slash and thus not retrieving the property-def, therefore line 82 fails get the qname.
when I put two slashes as below, it retrieves correctly.
line 81: let $property-def := $options-xml//:property-defs/:property[@name = $property-name]
line 82: let $qname := fn:QName($property-def/@namespace, $property-def/@localname)
