[CURIE] editorial suggestion

It would be useful to have an example of CURIE syntax solving the 
IPTC issue, since the introduction has 2 paragraphs decribing the problem,
but not the solution.

Or perhaps the problem itself could be explained better by example,
for instance saying something like 
[[
the IPTC would like to have a typed schema that allows both

<TopicSetRef TopicSet="urn:newsml:iptc.org:iptc:20001006:IptcSubjectCodes"/>

and

<TopicSetRef TopicSet="iptc:10112244"/>"

i.e. one attribute type that allows both syntaxes. QNames don't work, so we're
introducing CURIES.
]]

Or something like that, if I understand correctly.
