XmlSchema - validation trouble - .Net problem?

[AlexS]

Hello,

I have error when reading schema using XmlSchema. Read and then .Compile:

System.Xml.Sche ma.XmlSchemaExc eption: May not be nominated as the
{substitution
group affiliation} of any other declaration. An error occurred at , (11, 3).
Schema compile error:
System.Exceptio n: Schema error ---> System.Xml.Sche ma.XmlSchemaExc eption:
May no
t be nominated as the {substitution group affiliation} of any other
declaration.
An error occurred at , (11, 3).

When I look at failing line I see:

<element id="pfsInc" name="Inc" type="xi:monIte mType"
substitutionGro up="xi:item" />

Element item is defined as

<element name="item" type="anySimple Type" abstract="true" />

What is wrong here?

Why error message doesn't specify exacly which file at error occured?

It doesn't matter if I specify abstract="true" or remove it.

Anybody can help to find the answer? As per W3 it should work. However
doesn't.

Code I use is simple:

fn=schemaFileNa meString;
FileStream fs=new FileStream(fn,F ileMode.Open);

XmlSchema xsd=null;

try {

xsd=XmlSchema.R ead(fs,new ValidationEvent Handler(SchemaE rrorHandler));

}

catch (Exception ex) {

Console.WriteLi ne("Schema read
exception:{0}{1 }",Environment. NewLine,ex.ToSt ring());

Console.WriteLi ne("Schema read failed.");

return;

}

finally {

fs.Close();

fs=null;

}

// compile schema

try {

xsd.Compile(new ValidationEvent Handler(SchemaE rrorHandler));

}

catch (Exception ex) {

Console.WriteLi ne("Schema compile error:{0}{1}",

Environment.New Line,

ex.ToString());

return;

}

Test schema file

<?xml version="1.0"?>
<schema targetNamespace ="instance" xmlns:xi="insta nce"
xmlns="http://www.w3.org/2001/XMLSchema" elementFormDefa ult="qualified" >
<simpleType name="monT">
<restriction base="decimal"/>
</simpleType>
<simpleType name="shaT">
<restriction base="decimal">
<minInclusive value="0"/>
</restriction>
</simpleType>
<element name="itemAbs" type="anySimple Type" />
<!-- element name="item" type="anySimple Type"
substitutionGro up="xi:itemAbs " / -->
<element name="Inc" type="xi:monT" substitutionGro up="xi:itemAbs "/>
<element name="Dec" type="xi:shaT" />
</schema>

Anybody can point me in right direction? How can I define substitution group
in a way compatible with .Net?

Thanks!
Alex

Re: XmlSchema - validation trouble - .Net problem? - or w3.org xsd docs problem?

This schema is NOT valid. There are several things wrong with it such as the
fact that you reference complex types such as "xs:annotat ed" and "xs:facet"
which are not defined in an imported schema for the
"http://www.w3.org/2001/XMLSchema" namespace. However, even if you did do
this I would suggest not trying to define interactions between user-defined
types and types defined in the schema for Schema because the schema for
Schema isn't actually a valid schema according to the rules specified in the
W3C XML Schema recommendation.

Re: XmlSchema - validation trouble - .Net problem? - or w3.org xsd docs problem?

Dare,

here are 2 examples of schema: first one is validated Ok, and second one
fails. I have to process original schema as in second one. I can't change it
and I did not create it. And creators insist that schema is Ok.

The difference is that second schema uses substitutionGro up. And .net
validator fails over it.
At the same time, second variant is validated Ok by
http://apps.gotdotnet.com/xmltools/xsdvalidator/.

variant which passes XmlSchema.Compi le:
<schema targetNamespace ="sch" xmlns:xs="sch"
xmlns="http://www.w3.org/2001/XMLSchema" >

<simpleType name="monetary" >
<restriction base="decimal"/>
</simpleType>
<simpleType name="shares">
<restriction base="decimal">
<minInclusive value="0"/>
</restriction>
</simpleType>

<element name="item-abs" type="decimal" abstract="true" />

<element id="iascf-pfs_WorkProgres s" name="WorkProgr ess"
type="xs:moneta ry" />
<element id="iascf-pfs_WarrantyPro visionNonCurren t"
name="WarrantyP rovisionNonCurr ent" type="xs:moneta ry" />
</schema>

Variant, which fails in XmlSchema.Compi le and passes in xsdvalidator:
<schema targetNamespace ="sch" xmlns:xs="sch"
xmlns="http://www.w3.org/2001/XMLSchema" >

<simpleType name="monetary" >
<restriction base="decimal"/>
</simpleType>
<simpleType name="shares">
<restriction base="decimal">
<minInclusive value="0"/>
</restriction>
</simpleType>

<element name="item-abs" type="decimal" abstract="true" />

<element id="iascf-pfs_WorkProgres s" name="WorkProgr ess"
type="xs:moneta ry" substitutionGro up="xs:item-abs"/>
<element id="iascf-pfs_WarrantyPro visionNonCurren t"
name="WarrantyP rovisionNonCurr ent" type="xs:moneta ry"
substitutionGro up="xs:item-abs" />
</schema>

When I check what w3.org says on subtitution groups - I don't see why second
schema should fail.

Can you explain (or point out where I can see explanation for this) why
second variant fails in XmlSchema.Compi le?

To me it looks like bug in .Net. Or where?

Sorry, if my previous example was not completely Ok. I hope this one is more
clear

Btw, would you mind to explain a bit what you mean by "...because the schema
