XML Schema validation with complex type

[BAbram]

Hi all,

Let say I have the following XML snippet:

<SubRoot>
<One/>
<Two/>
</SubRoot>


This part is validated against the following schema (relevant part):


<xs:element name="SubRoot" minOccurs="0">
<xs:complexType>
<xs:sequence>
<xs:element name="One" type="sdt:d_Double"/>
<xs:element name="Two" type="sdt:d_String"/>

</xs:sequence>
</xs:complexType>
</xs:element>


The types are defined as:


<xsd:simpleType name="d_Double">
<xsd:restriction base="xsd:double">
</xsd:restriction>
</xsd:simpleType>

<xsd:simpleType name="d_String">
<xsd:restriction base="xsd:string">
</xsd:restriction>
</xsd:simpleType>


Now, this validation fails since <One> is a "double" and the tag is empty... If I would change it to type string it works fine. Does anyone know why this is? Also any pointer to where I could find information about validation and what would be the expected result in a case like this (for various types).

Thank you
Bjorn

I guess because "" is a valid string, whereas its not a double. W3C is always a good place to start looking for info:
