xsltc does not convert NodeList to internal node-set type

           Summary: xsltc does not convert NodeList to internal node-set
                    type
           Product: XalanJ2
           Version: CurrentCVS
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Enhancement
          Priority: Other
         Component: org.apache.xalan.xsltc
        AssignedTo: [EMAIL PROTECTED]
        ReportedBy: [EMAIL PROTECTED]


This problem was reported by Ferdinand O Shahagun ([EMAIL PROTECTED]).

With the xsl and Java extension function shown below, xsltc is giving 

       Unable to resolve call to function
'http://xml.apache.org/xslt/java:tapIt'.

According to Santiago Pericas, the problem here is that xsltc does not support 
conversions from NodeList to our internal node-set type. This should be added 
as an enhancement: the way to implement this is to create a DOM from the 
NodeList and then to get a ChildIterator from the DOM using the root node as 
the context node. 

In the meantime, Santiago has added a more informative error message 
to spell out the problem with type conversion.
