Yes, but of course EXSLT provides this without a static type in sight.

EXSLT also provides regex, and I'm sure this is a far friendlier solution than fiddling with facets.

You mean, for instance, reading numbers such as "1.000.000,00" from text?
I think a set of conversion functions that sit on top of EXSLT regex could provide this.

Agreed.
