[xquery-talk] Default element namespace: multiple declarations

[Ghislain Fourny]

Dear Mike,

That's a good catch.

If we want to "save the spirit of the spec" while stretching its letter reasonably, my interpretation of

  "The schema import may [...] declare that target namespace to be the default element/type namespace"

is that a schema import that declares a default element/type namespace also literally constitutes a "default element/type namespace declaration" in an extended sense (in addition to the "vanilla" default element/type namespace declarations of 4.14).

As a consequence, my interpretation of

"A Prolog may contain at most one default element/type namespace declaration [err:XQST0066]."

would speak in favor of throwing XQST0066 for the query below.

Does this reasoning make sense?

Kind regards,
Ghislain
