Yes. That's the point. Isn't it a good thing they're in different
namespaces? :-)

In effect, the HPC app Executable requires (without saying this) that
you don't use the PATH to select the binary to run. That's fine for
their specific goal (demonstrating interop across a lot of systems) but
I suspect that it is too restrictive for many interesting uses. To my
mind, that just means that there's room for an "HPC Level 2 Profile"
sometime. :-)

No, because (IIRC) that's not (technically) type-compatible. This is
because we specified that there can only be one xsd:any##other child of
the JSDL Application element.

Donal.
