No, there isn't a better approach. Some functions like this were proposed
during XSLT 2.0 development, but the general view was that formatting ASCII
layouts using fixed-width fonts was not a significant use case. Even though
email still seems incapable of handling much else.

Subject: [xsl] Is there a better way for doing printf() in XSLT?
Trying to improve the readability of an XML file I've come up
with some templates (below, part 1) which produce the output
shown at the end. As this works fine, the only question I
have whether this is the best one can do in XSLT 2, or did I
miss some cuter approach?
Thanks
