The quality of an element having a unique identifier is not accomplished at 
all through the name of the attribute, only through the type of the attribute.

I suspect your document type definition in your document type declaration 
is missing even just a single line to declare the attribute as being of 
type ID.

I often add something along the lines of the following to my documents to 
get the ID to work:

   <!DOCTYPE doc
   [
   <!ATTLIST my-element id ID #REQUIRED>
   ]
   <doc>.....

or:

   <!DOCTYPE sales
   [
   <!ATTLIST customer custNo ID #REQUIRED>
   ]
   <sales>.....

I hope this helps.
