Schema derived type and the base type

bonekrusher · January 7th, 2008, 07:46 PM

Hi,

I recently bought Word 2007 to try its XML support. When I try to import my schema I receive an error:

"Schema derived type and the base type must have the same content type"

Its pointing to a complexType element that is mixed:

Code:

<xs:complexType name="texttype" mixed="true">
        <xs:choice minOccurs="0" maxOccurs="unbounded">
            <xs:element ref="bold" minOccurs="0" maxOccurs="unbounded"/>
            <xs:element ref="italic" minOccurs="0" maxOccurs="unbounded"/>
            <xs:element ref="UnderScore" minOccurs="0" maxOccurs="unbounded"/>

My Schema are valid, does anyone know why I am receiving the error?

You might be trying to extend a mixes type with a none mixed type. What elements are you defining that extend "texttype". Try adding mixed="true" to them as well.

Well, either the schema is valid, in which case Word 2007 is wrong, or its invalid, in which case you are wrong. Since you haven't said what makes you think it is valid, and since you haven't supplied enough of the schema for anyone else to come up with an opinion on the matter, the rest of us will have to keep an open mind.

Sam & Michael,

Thank you for your help. Sam was correct.

As for validation, I am using xmlSPY and it validated before I fixed the problem.

Thanks for the help.

I hate to be blunt, but it is a common error to think that because XMLSpy accepts a schema, the schema is therefore valid. You should never accept a schema as valid until you've put it through two or three XML schema processors, one of which should be Xerces.

Hi Michael,

Blunt is good, you are correct. It is a good practice.

As always, thanks for your help.
