p:make-uris-absolute

Jeni proposes[1]

Another step that I remember Henry mentioning at the F2F many moons ago 
was a 'make-uris-absolute' step like this:

<p:declare-step type="p:make-uris-absolute">
   <p:input port="source" />
   <p:output port="result" />
   <p:option name="match" required="yes" />
</p:declare-step>

The result of this step is a document that's identical to the source 
document, except for the attributes and elements matched by the match 
pattern. Any attribute or element matched by the match pattern is 
interpreted as a URI, and is turned into an absolute URI based on the 
base URI of its parent element (if the matched node is an attribute) or 
the element itself (if the matched node is an element). If the matched 
node is an element, the string value of the element is used as the 
relative URI, and the only content of the copy of the element will be a 
single text node child with the value of the absolute URI.

                                        Be seeing you,
                                          norm
