Dear all,

while working through the NIST test cases I found schemas that assumed a
huge range for floats and doubles. For example the schema
NISTSchema-double-minExclusive-1.xsd has the facet <minExclusive value="1E-1075"/>.

Studying the IEEE 754 specification I came the conclusion that the exponent
in this NIST schema is much too great. For doubles the exponent must be
smaller than 308. Right?

Thanks for your attention,
