VS barks at this recursive schema

[n_o_s_p_a__m]

Can some one help me out here, VS doesn't like this schema ("SubSystem
is not defined"). Anyone know why?

<xs:complexType name="SystemType">
<xs:sequence maxOccurs="unbounded">
<xs:choice maxOccurs="unbounded">
<xs:element minOccurs="0" maxOccurs="unbounded"
name="SubSystem">
<xs:complexType>
<xs:sequence>
<xs:element ref="Operation" minOccurs="0" maxOccurs="unbounded"/>
<xs:element ref="SubSystem" minOccurs="0" maxOccurs="unbounded"/>
</xs:sequence>
<xs:attribute ref="SubSystemId" />
<xs:attribute ref="SystemId" />
</xs:complexType>
</xs:element>
<xs:element ref="Operation" />
</xs:choice>
</xs:sequence>
<xs:attribute ref="SystemId" />
<xs:attribute ref="Name" />
</xs:complexType>

Hello!

Have you tried this? IIRC this works:

<xs:complexType name="SystemType">
<xs:sequence maxOccurs="unbounded">
<xs:choice maxOccurs="unbounded">
<xs:element ref="SubSystem" />
<xs:element ref="Operation" />
</xs:choice>
</xs:sequence>
<xs:attribute ref="SystemId" />
<xs:attribute ref="Name" />
</xs:complexType>

<xs:element minOccurs="0" maxOccurs="unbounded" name="SubSystem">
<xs:complexType>
<xs:sequence>
<xs:element ref="Operation" minOccurs="0" maxOccurs="unbounded"/>
<xs:element ref="SubSystem" minOccurs="0" maxOccurs="unbounded"/>
</xs:sequence>
<xs:attribute ref="SubSystemId" />
<xs:attribute ref="SystemId" />
</xs:complexType>
</xs:element>

Hi Pascal,

Yes that works and I thank you.

I am curious if it my XSD is breaking some composition rule in the
standard, or if this is a VS-only thing.

I don't know (there seems to be nothing written about...) but I guess it
has something to do with the scope of the definitions...

But it may also be a "VS thing" as Visual Studio does not understand all
of XSD.

Looks like a shortcoming of "russian doll" xsd design, not VS.

"Salami slice" style works fine.

A good article I found:
