hexBinary type

["Eran Balter" <E.Balter@F5.com>]

Hi,

 

I am validating the following instance:

 

<hexBinary>0Fb8</hexBinary>

 

with the following schema:

 

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">

        <xsd:element name="hexBinary">

                <xsd:simpleType>

                        <xsd:restriction base="xsd:hexBinary">

                                <xsd:enumeration value="0FB8"/>

                        </xsd:restriction>

         </xsd:simpleType>

        </xsd:element>

</xsd:schema>

 

The instance has the small “b” while the enumeration permits the capital “B”.

 

Is it a valid instance? (the standard claims: “The canonical representation for hexBinary is defined by prohibiting certain options from the Lexical Representation (§3.2.15.1). Specifically, the lower case hexadecimal digits ([a-f]) are not allowed.”). libxml2 claims it’s valid, while xerces claims it’s not.

 

TIA,

Eran
