Name of notation used in conjunction with XML Schema

Question

I'm looking for the name for this style of literal, containing the full namespace URI in curly brackets followed by the identifier name.

{http://www.w3.org/2001/XMLSchema}dateTime

Answer 1

It's a notation introduced by James Clark and quite commonly used; for example this is how QNames are passed as parameter names in the JAXP API specification. It's not standardized, and it's probably most often referred to as "Clark notation".

Answer 2

Interesting question, I've never seen that form of notation before. A quick google for "xml namepsace in curly braces" threw up this site: http://www.jclark.com/xml/xmlns.htm

It looks like 'universal name' or 'extended data model' might be the terms you're looking for. The author of the linked article also suggests that the { } form isn't used because it's incompatible with XML 1.0.
