Hello David,

So,

    {http://www.w3.org/2005/xqt-errors} FOER0001
    {http://www.w3.org/2005/xqt-errors} FOER0002
    {http://www.w3.org/2005/xqt-errors} FOER0003
    ...

is not an XML vocabulary but,

    {http://www.bookstore.org}BookStore
    {http://www.bookstore.org}Book
    {http://www.bookstore.org}Author
    ...

is an XML vocabulary?

Why?

What distinguishes them that allows me to know this?

So the first set of xs:QNames is not an XML vocabulary but the second set of xs:QNames is an XML vocabulary?

Why?

I thought that -- by definition -- an XML vocabulary is a set of xs:QNames, where each local part has the same namespace URI part.

No?
