Thanks all...
This gives me something to go on.
I did "try" mikes suggestion in a novice way 
" is to use the string-value of the element node, rather than its text node

by writing:

<template match="NODE/string()" >

Which should obviously work right ?  Matches the entire string contents of
NODE concatenating silly chunked up adjacent text and removes commands and
PI's ...

Ha silly me.

I will take to heart the reason WHY I think I need to match on text() ...
maybe I don't.
I won't go into details right now, I'm looking more in directions to
investigate and learn rather than solutions to my problem.

Thanks all

In principle, an element node is not allowed to have two adjacent text 
node children, so unless there are comments or processing instructions 
breaking up the text, it should be delivered as a single node.

However, DOM does allow adjacent text nodes, and some processors work on 
a DOM tree as input, and I suspect some processors do not always 
amalgamate adjacent text nodes as they should.

In any case, it's a good idea to make sure that your code still works if 
someone puts a comment in the middle of the text, so it's best not to 
assume that all the text of an element is in a single node. Usually the 
best way of doing that (unless you are dealing with mixed content) is to 
use the string-value of the element node, rather than its text node
