Winged Horse - implementation-defined?

In XQuery, "2.4.4 SequenceType Matching" says:

    In this case, an implementation is allowed (but is not
    required) to provide an implementation-dependent
    mechanism for determining whether the unknown
    type is compatible with the expected type".

This should be implementation-defined. An implementation
should document whether it provides such a mechanism, and the
mechanism it uses (generally, to rely on information in the
PSVI).
