   RE: [xml-dev] The subsetting has begun

[ Lists Home | Date Index | Thread Index ]

Thanks Gavin.  For the kinds of subsets being 
discussed, is a 'syntax-only' specification 
the only kind of spec needed?   I grant 
that works for XML but it opens up the 
question, is a proper subset of XML 1.0 
really what is being asked for by those 
asking for a subset?  Or are they asking 
for a syntax subset plus a matching infoset?

I'd remove namespaces, the infoset, xml:space, xml:lang and xml:base.

In the case of namespaces, xml:space, xml:lang, and xml:base: these are markup 
constructs that needn't be standardized in the *syntax* specification, but 
should instead be defined at a higher level. 

The infoset is similar: the information gleaned from an XML document is 
necessarily application-specific, and as such, there is no need to make a 
single abstract set of information canonical.
