Re: [xml-dev] James Clark: XML versus the Web

[COUTHURES Alain <alain.couthures@agencexml.com>]

These are features to be considered for XML 2.0 because it's not 
bearable that JSON might be richer than XML for such points.

I'm now considering similar XPath extensions to deal with JSON in 
XForms. The points to address are about multiple roots, element names, 
arrays and data types.

I'm now writing a paper for XML Prague 2011 about that. My XForms 
implementation (XSLTForms) doesn't have to wait for XML 2.0 because it 
has its own XPath parser written in XSLT 1.0 and XPath engine written in 
Javascript.

Usually, I think it's simpler to map JSON objects just using elements 
and let attributes for metadata.

Within XPath, element names shouldn't be quoted as string so ` character 
could have to be used instead. For types, xsi:type sounds great.

XPath 2.0 sequences sound like JSON arrays, don't they?

Well, my paper is not yet finished... ;-)

Cheers
