What is the default visibility of a package component inside the
declaring package, if the component has no "visibility" attribute
specified on its declaration?

I believe that the default visibility should be "public", however I
couldn't find any statement about this in the latest XSLT 3.0
specification.

So, could someone confirm my guess, and/or point the text in the Spec
that explains this?

If there isn't really such definition, I believe it needs to be added
to the specification.
