Description

We should add a new XPath ItemType for external JavaScript objects, so that type information for variables, etc. can be more specific than just item(). e.g. for storing JavaScript objects returned from calling IXSL extension functions, and global JS functions. (And to avoid conversion to XDM types, where this would otherwise happen.)

For Java, the type of an external object of class org.package.ClassName is

Q{http://saxon.sf.net/java-type}org.package.ClassName

(It can of course be written as a lexical QName with a prefix if preferred.)

For JavaScript, I think we should use a single QName for all external objects, and suggest the name

Q{http://saxon.sf.net/javascript-type}Object

The alphacode for an external Java object type is "X norg.package.ClassName". For JavaScript I think it can simply be "X".
