This is one of the aims of the integration between XSLT and XML Schema
that
comes with XSLT 2.0.
Unfortunately, despite an immensely complex type system designed to
achieve
this integration, the simple goal of spotting spelling mistakes in path
expressions isn't fully achieved, because rules in stylesheets can't be
tied
statically to specific documents. However, I would expect that XSLT 2.0
implementations will fill this gap by at least giving you warnings.

This is interesting. Assuming v2.0 is backwardly compatible, presumably I
could just run my existing transform through a suitable processor (changing
the version at the top of the XSLT script) and get the warnings I want.
I notice the latest version of Saxon implements the XSLT 2.0 specification
but you didn't suggest using it. Does it not currently integrate with Schema
in this way, or not give warnings when rules are violated?
Thanks,
Mike
