Is the below valid? I would like to create the following in xml.

EG
<Scores>
<Score num="1">50<Score>
<Score num="2">45<Score>
<Score num="3">76<Score>
</Scores>

The schema for this is below. It is only possible to create this in Stylus Studio if you add 'type' to the element 'Score' manually. The WYSIWYG interface won't allow you to do this. Instead it removes the attribute so you can then enter a type.

Now for the strange part. If I validate this using C++ the schema is valid, but if I do the same but using visual basic 6 the schema produces an error when loaded. The error shown points to a type with an attribute complex type.

Am I missing some schema rules here. Can someone explain.

<xsd:element name="Scores" maxOccurs="1">
<xsd:complexType>
<xsd:sequence>
<xsd:element ref="Score" maxOccurs="25" minOccurs="1"/>
</xsd:sequence>
</xsd:complexType>
</xsd:element>

<xsd:element name="Score" type="xsd:long">
<xsd:complexType>
<xsd:attribute name="Position" type="xsd:long"/>
</xsd:complexType>
</xsd:element>

That schema is wrong; you can't assign a type to Score and also define a local complexType for it. You need to change the definition of Score into:

<xsd:element name="Score">
<xsd:complexType>
<xsd:simpleContent>
<xsd:extension base="xsd:long">
<xsd:attribute name="Position" type="xsd:long"/>
</xsd:extension>
</xsd:simpleContent>
</xsd:complexType>
</xsd:element>
