Hi,
I am trying to read the Type of an element ie. integer type, however, i
have 2 results depending whether i declare my xml instance with a using
a "noNamespaceSchemaLocation" or a "schemaLocation" attribute.
If i declare xml instance with a "noNamespaceSchemaLocation" attribute,
i would get the right type i.e. java.math.BigInteger, however if i
declare the xml instance with a "schemaLocation" attribute, then i will
get a java.lang.String which is incorrect.
Is this a bug or a feature? did i miss something? would be grateful if
someone could help to shed some light... Below are the details of the
schema, xml-instance and my java app. am using dom4j v 1.3
Thanks in advance..

schema
---------
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema";
targetNamespace="http://my.integer.org";
elementFormDefault="qualified">
<xsd:element name="myInfo">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="myInteger" type="xsd:integer"/>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:schema>
xml-instance with noNamespace
------------------------------------------
<myInfo
xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'

<myInteger>5</myInteger>
</myInfo>
xml-instance with namespace
--------------------------------------
<myInfo xmlns='http://my.integer.org'
