format number question

Problem: If the number exist's, and if there leading zeros, drop them. Ex:
054 --> 54, else "" (nothing).
I did the following:
At the top:
<xsl:decimal-format name="staff" NaN="" />

In the body:
<xsl:value-of select='format-number(AAA,"###","staff")'/>

I make the assumption that if there are any characters in this field, then
they are numbers.
This also handles the case where only line-feeds and tabs come in.
I have run various test's without any problems or wierd results.

Question: Anyone see any problems with this?

Side note. I can't believe that this is not discussed in the various FAQ's.
As suggested, I tried to search the mulberrytech site. All searches came
back as not found. Even when I entered NaN. I'm probably not entering
something correctly.
went to Dave Pawson's site but was unable to locate the search engine.

Thanks in advance for comments.
