Summary: PF pf:attribute error for function parameter without type
Initial Comment:
Given the query
declare function getData($d) { $d//[EMAIL PROTECTED]"1"] };
let $d := <b><c><data num="1">211098</data></c></b>
return <result>{getData($d)}</result>
MPS-version gives the error message
!type error: no variant of function pf:attribute accepts the given argument
type(s): item*; string; string; string; string; string
!type error: maybe you meant: !type error: pf:attribute (node*, string, string,
string, string, string) as node* !type error: illegal arguments for function
pf:attribute !# halted in typecheck.brg (fun_not_found), line 1317
Algebra-version gives the error message "fatal error: Sorry, I cannot translate
the test for type `node*'"
The problem lies in the fact that in this query, the parameter $d has no
specified type, while in the body we refer to an attribute. Is we write
declare function getData($d as element()) { $d//[EMAIL PROTECTED]"1"] };
let $d := <b><c><data num="1">211098</data></c></b>
return <result>{getData($d)}</result>
The query compiles and runs fine.
