In the Sun ElemDecl test set, tests

   <test set="ElemDecl" group="valueconstraint00501m1" name="Positive"/>
   <test set="ElemDecl" group="valueconstraint00501m2" name="Positive"/>

the essence of the test is to check that the fixed value declared for an
element is valid against the definition of the type invoked using xsi:type. The
rules state that the canonical lexical representation of the fixed value must
be valid against this type. In these two tests the fixed value is a floating
point value. Although Part 2 defines a "canonical representation" for float and
double, it is not truly canonical, in that multiple representations are
permitted. Specifically, an implementation can return 9.999999776482582E-3 as
the canonical representation of the value 0.01, and this will violate the
pattern facet, causing the instance to be invalid.
