XML Schemata , xsd-compiler and undefined data type

[EDN Admin]

Hello everybody.

I have a bunch of XML files from which I want to generate XSD Schema files.

Consider I have one XMLschema starting with

<div style="color:black; background-color:white
<pre><span style="color:blue <<span style="color:#a31515 Schema <span style="color:red name<span style="color:blue =<span style="color:black "<span style="color:blue FDTDataTypesSchema<span style="color:black " <span style="color:red xmlns<span style="color:blue =<span style="color:black "<span style="color:blue urn:schemas-microsoft-com:xml-data<span style="color:black " <span style="color:red xmlns:dt<span style="color:blue =<span style="color:black "<span style="color:blue urn:schemas-microsoft-com:datatypes<span style="color:black "<span style="color:blue >
<span style="color:blue <<span style="color:#a31515 AttributeType <span style="color:red name<span style="color:blue =<span style="color:black "<span style="color:blue nodeId<span style="color:black " <span style="color:red dt:type<span style="color:blue =<span style="color:black "<span style="color:blue id<span style="color:black "<span style="color:blue />
[/code]


<br/>
and so on.
Now I have another XML schema where the type nodeId is referenced, which begins as follows:

<div style="color:black; background-color:white
<pre><span style="color:blue <<span style="color:#a31515 Schema <span style="color:red name<span style="color:blue =<span style="color:black "<span style="color:blue FDTHARTCommunicationSchema<span style="color:black " <span style="color:red xmlns<span style="color:blue =<span style="color:black "<span style="color:blue urn:schemas-microsoft-com:xml-data<span style="color:black " <span style="color:red <br/> xmlns:dt<span style="color:blue =<span style="color:black "<span style="color:blue urn:schemas-microsoft-com:datatypes<span style="color:black " <span style="color:red xmlns:fdt<span style="color:blue =<span style="color:black "<span style="color:blue x-schema:FDTDataTypesSchema.xml<span style="color:black "<span style="color:blue >
<span style="color:blue <<span style="color:#a31515 ElementType <span style="color:red name<span style="color:blue =<span style="color:black "<span style="color:blue CommandResponse<span style="color:black " <span style="color:red content<span style="color:blue =<span style="color:black "<span style="color:blue empty<span style="color:black " <span style="color:red model<span style="color:blue =<span style="color:black "<span style="color:blue closed<span style="color:black "<span style="color:blue >
<span style="color:blue <<span style="color:#a31515 attribute <span style="color:red type<span style="color:blue =<span style="color:black "<span style="color:blue fdt:nodeId<span style="color:black " <span style="color:red required<span style="color:blue =<span style="color:black "<span style="color:blue no<span style="color:black "<span style="color:blue />
<span style="color:blue <<span style="color:#a31515 attribute <span style="color:red type<span style="color:blue =<span style="color:black "<span style="color:blue value<span style="color:black " <span style="color:red required<span style="color:blue =<span style="color:black "<span style="color:blue yes<span style="color:black "<span style="color:blue />
</ElementType>

[/code]


<br/>
Now for the problem: Although both files resist in the same directory, and the nodeId type is defined in the namespace "fdt", the xsd.exe utility complains with

<pre>C:develdocfdtv12XML-Files>xsd FDTHARTCommunicationSchema.xml
Microsoft (R) Xml Schemas/DataTypes support utility
[Microsoft (R) .NET Framework, Version 4.0.30319.1]
Copyright (C) Microsoft Corporation. All rights reserved.
Error: There was an error processing FDTHARTCommunicationSchema.xml.
- Undefined data type: fdt:nodeId.

If you would like more help, please type "xsd /?".[/code]

<br/>
Does anybody have a clue, whats wrong here?

Matthias
