Part of the alignment of Turtle with SPARQL 1.0 and SPARQL 1.1, both
of which allow for local names that start with digits. The RDF data
model has always allowed for any IRI to be used, this in fact meant
that there is valid RDF that cannot be expressed in RDF/XML.

Thank you for your comment. I hope that clears up your question.

Cheers,
Gavin
