[Monetdb-developers] Data type of the text() nodes

Hello, I'm having a problem with the data type of text() nodes in XRPC implementation. --------------------------- module function definition: --------------------------- module namespace foo = "xrpc-test-function"; declare function foo:q2($strs as xs:string*) as node()* { for $s in $strs return <bar>{$s}</bar> }; ----------- test query: ----------- import module namespace test = "xrpc-test-function" at "/ufs/zhang/max-nr-params/xrpc-mod.xq"; let $hello := <hello> <lang>en</lang> <lang>nl</lang> </hello> let $lang := $hello/lang/text() return execute at {"localhost"} {test:q2($lang)} ------------------------------------------------------------- I got the error "function could not be resolved" when I run the XRPC query above. The reason is that all items in the sequence $lang have the type U_A (xs:untypedAtomic), and they are marshalled in the XRPC req. msg as, for example: en At the server side, the values are unmarshalled and assigned the type U_A again. So far, the values are handled correctly, IMHO. But then problem happens, namely, when the server calls the function 'xquery_sig_match' (in pathfinder.mx), it concludes that xs:untypedAtomic is not a sub-type of xs:string, hence, the function signature can not be resolved. This error does not occur if the function 'q2' is called without XRPC. So, what is the trick of pathfinder to match the signature? Is xs:untypedAtomic just treated the same as xs:string? The easiest solution of my problem is to just marshall an xs:untypedAtomic as an xs:string, but if someone has better suggestions, I would like to know. Thanks a lot! Regards, Jennie
