Description

for example,
if I am constraining a float type with a facet minInclusive = "-0",
the getLexicalFacetVAlue gives 0.0E1 as value of this facet.

The http://www.w3.org/TR/2001/REC-xmlschema-2-20010502 recommends :

"The special values positive and negative zero, positive and negative infinity and not-a-number have lexical representations 0, -0, INF, -INF and NaN, respectively"

These special values must not be changed, else it would be a semantic change
