xsd condition

[Lucia]

Hello,

I'd like to write an XML-Schema which has the following structure:

<xsd: complexType name="example">
<xsd: element name="variablename" type="xsd:string"/>
<xsd: element name="variabletype" type="xsd:string"/>
<xsd: element name="variablevalue" type=?????????? />
</xsd:complexType>

My problem is that the type of the element "variablevalue" depends on
the content of the element "variabletype".

e.g. when variablevalue=long, the type of variablevalue should be
"xsd: long";
when variablevalue=string, the type of variablevalue should be
"xsd: string";

How can solve this problem? Have you any idea?

Thanks

lucia

Create a simpleType for each of the possible variable types and then use
xsd:union or xsd:choice to combine them.
