Re: [xml-dev] Multiple instances of an attribute Re: [xml-dev]Towards XM

[Stephen Green <stephengreenubl@gmail.com>]

I'm also thinking how the XML Namespaces spec used notation like xmlns:a=...
so I could imagine something like <price xml2ul:amount='["100 GBP',
'200 USD']'/>
for unordered lists where xml2ul is a WG-defined reserved prefix like xmlns
Likewise for sequences or ordered lists (ol) maybe
<text xml2ol:font-family='["Arial", "Verdana"]'/>
where the order is significant.

I guess someone can think of something better...
