Hello.

     The Xalan-J project has three XPath APIs:  the JAXP XPath API,[1] the 
DOM Level 3 XPath API,[2,3] and the processor-specific Xalan-J XPath 
API.[4,5]

     The Xalan-J XPath API filled a need, as it existed before any 
standard specification for an XPath API was available.  Now that JCP has 
defined a standard Java XPath API and the W3C has given a strong 
indication of the form of a DOM XPath API (though not a recommendation), 
it might be time to deprecate the Xalan-J XPath API.  I'd like to solicit 
any views for or against the idea.

     See [6] for information about what it means for an API to be 
considered to be a public API of Xalan-J.

Thanks,

Henry
