XML Link Questions

[Neil Bradley]

Having read the XML Link specification, I have a few questions.

In both the XML Language and XML Link schemes, a target element can 
be identified by its ID value. Is it possible using XML Link to 
target an element in a document that does not have a DTD, and if so, 
how is the target attribute identified, by a fixed attribute name 
of 'Id'?

Does STRING(1,'testing',0) only select the first character of 
'testing', or the whole word. If the first character, can DITTO() be 
used to specify a range from 't' to 'g', and is DITTO() assumed to 
start from the enclosing element or from the first character of 
testing, in which case can DITTO() actually find it?

What impact does case-sensitivity have on the default and replacement 
attribute names and values. Is 'HREF' or 'href' the default resource 
locator name, and must 'XML-ATTRIBUTES' (or 'xml-attributes') contain 
case-sensitive values ('HREF TARGET TITLE REFTITLE' or 'href target 
title RefTitle').
