---------------------------------
Hi Khaled,
Yes, you are right. Because NaN ≠ NaN, including NaN in an enumeration does not
have the effect of accepting NaNs as instances of the enumerated type. Thanks.

> schema doesn't support NaN in enumeration for precisionDecimal.
> example:
> XSD
> <?xml version="1.0"?>
> <schema xmlns="http://www.w3.org/2001/XMLSchema";
> targetNamespace="http://www.schemaTest.org/schema11";
> xmlns:sv="http://www.schemaTest.org/schema11";>

> </restriction>
> </simpleType>
> <element name="root">
> <complexType>
> <sequence>
> <element name="Special1" type="sv:pSpecial"
> minOccurs="1" maxOccurs="unbounded"/>
> </sequence>
> </complexType>
> </element>
> </schema>

> patch. Thanks.
