[closed] RDF Core LC issue xmlsch-09

Colleagues,

The RDF Core WG has considered your last call comment captured in

   http://www.w3.org/2001/sw/RDFCore/20030123-issues/#xmlsch-09

(raised in section "4.2. QNames (Editorial, but important)" of
from http://lists.w3.org/Archives/Public/www-rdf-comments/2003JanMar/0489.html )

and decided

   http://lists.w3.org/Archives/Public/w3c-rdfcore-wg/2003Mar/0138.html

to accept it giving the following explanation:

The RDF/XML syntax WD section referred to is paragraph 2 of
   http://www.w3.org/TR/2003/WD-rdf-syntax-grammar-20030123/#section-Syntax-intro
is the very first section in the document introducing the syntax
intended as an overview, not defining the grammar.

We accept that this paragraph could be misleading and imply that an
XML prefix, and thus only prefixed names, are required.  

We propose to amend the text in that paragraph to make it clear that
in a XML QName the prefix is optional where there is a default
namespace either by adding a note or rewording to remove the mention
of prefixes.

However, we note, the link [Qnames] in the section above already goes
to the following definition of QName:

    QName ::= (Prefix ':')? LocalPart
    Namespaces in XML
    -- http://www.w3.org/TR/1999/REC-xml-names-19990114/#NT-QName

which shows that the prefix part is optional in the current definiton
of QNames.

This is also mentioned in the errata:
     "Names with no colon can be qualified names."
      Namespaces in XML Errata
      -- http://www.w3.org/XML/xml-names-19990114-errata#NE10

We also peeked at XML 1.1 CR:
     QName ::= PrefixedName | UnprefixedName
     Namespaces in XML 1.1, W3C Candidate Recommendation 18 December 2002
     -- http://www.w3.org/TR/2002/CR-xml-names11-20021218/#NT-QName

which keeps the same distinction.
