Look in the Schema Datatypes  Proposed Rec at

http://www.w3.org/TR/xmlschema-2/#float

Especially, find the link for "patterns" in this part:

3.2.4.3 Constraining facets
float has the following constraining facets:

pattern
enumeration
whiteSpace
maxInclusive
maxExclusive
minInclusive
minExclusive

Start by hitting the "pattern" link and you will be led to the RE notation
they use.  It's expressed in BN form.

Cheers,
