I have described a keyboard in XML and I have an XSLT that will produce an 
SVG diagram rectangles representing each key of a keyboard with the scan 
code centered in the rectangle.
OK, I admit it, it is an ugly keyboard but that is besides the point!

Now I need to write another XSLT that will emit C++ source code: each array 
element will contain the upper left coordinates of the key and width and the 
height of the key. The array will be indexed by the scan code. I cannot 
figure how how to do this in one shot.

I think I could do it in two XSLTs. The first XSLT will emit each key as a 
single XML element with the scan code as the attribute. Then the second XSLT 
will sort by the scan code. Is there a bettery way?

Thanks,
Siegfried
