Test modules-28 expects error XQST0093. It should also allow XQST0054.

err:XQST0054

It is a static error if a variable depends on itself.

err:XQST0093

It is a static error to import a module M1 if there exists a sequence of modules M1 ... Mi ... M1 such that each module directly depends on the next module in the sequence (informally, if M1 depends on itself through some chain of module dependencies.)

One could argue that XQST0093 is preferred because it is more specific; but XQST0054 certainly seems acceptable, and in the case of static errors, we should give processors the benefit of the doubt.
