There are similar cases where I know they have interpreted the spec differently, for example see what happens with a format token of "C". I agree that a stricter reading of the spec would probably output "8" rather than "008" in your example. But the details of xsl:number output, when the format token isn't one of those specified (or to some extent even when it is) are left very much to the good sense of the implementator. For example, an implementation that (with format="999") represented 1 as 999 and 8 as 008 would be conformant, but not very useful. Michael Kay http://www.saxonica.com/
