Re: Emulation of XSL's id() in DSSSL?

Thank you Norman, but you haven't got my point;

Look at section 4.1 of the XPath-Spec. You can use the id()-function to 
resolve multiple references (seperated by space), thus
id("id1 id3 id5") returns a nodeset with the three nodes having id1, id3, and 
id5 as their id's.

>(element-with-id 'value') will return the element that has ID 'value'.

That's just the problem. I want to support multiple references. So I need a 
scheme function that breaks up a string into a list, using space as separator.
But my Scheme knowledge doesn't go that far.
