Summary: PF (Algebra): xs:untypedAtomic may occur for any atomic type
Initial Comment:
(This is relevant for the algebra back-end only. In
milprint_summer, xs:untypedAtomic == xs:string, which
circumvents the problem.)
The type xs:untypedAtomic is promotable to any atomic
type. Hence, it may be left as a statically possible
type for any (built-in) function with atomic arguments.
An implicit typeswitch (introduced by fs.brg) will
ensure that *dynamically* all items will have a
sensible type (not xs:untypedAtomic). From static
analysis, however, the compiler will see a possible
type of xs:untypedAtomic (i.e., a BAT for this type
when creating MIL code).
Examples are:
fn:string-join ((<a/>, "foo"), "bar)
(fn:string-join() is not yet implemented in the algebra
back-end, though)
declare function foo ($a as xs:string, $b as xs:
string)
{
fn:concat ($a, $b)
};
for $a in (<a/>, "foo") return foo ($a, "bar")
(without the user-defined function, the implicit
introduction of an fn:string() as required by the specs
call would hide our actual problem)
Currently, some built-ins (e.g., fn:concat()) complain
in that situation (e.g., there is an assertion testing
for aat_str in the implementation of fn:concat()). It
seems like we can simply drop the BAT for xs:
untypedAtomic (it will contain nils only due to the
typeswitch) in such cases. We have to be aware that
the BAT *may* be available when generating code.

This is still an issue --- at least the correct output has not yet been
provided / checked:

Jens, can you check the test output of the mps version and approve it if
it is correct?
You can then assign the bug to JR to fix the algebra version.

Since also the mps version fails I consider the a "release bug"; cf.
