Hello,

I'm not sure if it is a problem or new characteristic.

xsd files looks very different.

One year ago when I created schema from xml content I got a header like this:

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified">

and tags were like <xs:element name="" type="xs:string"/>

But, now I have gotten a different xsd file and header is like this:

<xsd:schema xmlns:xsd='http://www.w3.org/2001/XMLSchema'>

ans tags are:
<xsd:element name='idCorrida' type='xsd:string'></xsd:element>

How can I obtain the same header and same type of file?

is it important elementFormDefault="qualified"?
Are a check box to enable "elementFormDefault"?

Best regards.

Hi Fernando,

Which Stylus Studio version you have been running before?

The declaration you have posted is invalid, the attribute "name" cannot be empty

<xs:element name="" type="xs:string"/>

The latest release defaults to elementFormDefault="qualified" globally but depending on how the XML instance is shaped it does override the elementForm, for example given the following XML document

<a:books
xmlns:a="urn:xml:books">
<book>
<title>Java Web Services</title>
</book>
</a:books>

Stylus Studio generates

<xs:schema
xmlns:xs="http://www.w3.org/2001/XMLSchema"
elementFormDefault="qualified"
targetNamespace="urn:xml:books"
xmlns:a="urn:xml:books">
<xs:element name="books">
<xs:complexType>
<xs:sequence>
<xs:element name="book" form="unqualified">
<xs:complexType>
<xs:sequence>
<xs:element name="title" form="unqualified" type="xs:string"/>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>

Hope this helps

Ivan. Thanks for your answer.

I have XML Enterprise Edition 2006, Release 3 and JVM 1.5.0_0b.

and yes, you are correct. Name attribute has a value. But this is not the problem. The problem is Stylus nowadays is creating xsd files in different way.

I attach a new and old xsd files.

Thanks.

schema-10xml.xsd
New xsd file

DefPktRW-2.xsd
Old xsd file

Yes, in most recent Stylus Studio versions, the schema generator uses the Russian doll style unless an element appears in multiple contexts in which case it defines a global definition.

The following is a quite sophisticated example with an heterogeneous list of media

<?xml version="1.0"?>
<media
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="booksns3.xsd">
<book>
<title>Java Web Services</title>
<isbn>AAA</isbn>
</book>
<dvd>
<title>24 Hours</title>
</dvd>
<book>
<title>C# Web Services</title>
<isbn>BBB</isbn>
</book>
</media>

The resulting schema makes use of a common ancestor “title” then derives “book” from “title” and defines dvd as type title.

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified">
<xs:element name="media">
<xs:complexType>
<xs:choice maxOccurs="unbounded">
<xs:element ref="book"/>
<xs:element ref="dvd"/>
</xs:choice>
</xs:complexType>
</xs:element>
<xs:element name="book">
<xs:complexType>
<xs:complexContent>
<xs:extension base="title">
<xs:sequence>
<xs:element ref="isbn"/>
</xs:sequence>
</xs:extension>
</xs:complexContent>
</xs:complexType>
</xs:element>
<xs:element name="isbn" type="xs:NCName"/>
<xs:element name="dvd" type="title"/>
<xs:complexType name="title">
<xs:sequence>
<xs:element ref="title"/>
</xs:sequence>
</xs:complexType>
<xs:element name="title" type="xs:string"/>
</xs:schema>

Stylus Studio does not allow to change strategy for schema generation.
May I ask you why this constitute a problem?

Thanks Ivan.

I have a old internal-application that only uses old style.

are there any way that Stylus produces old style?

best regards.
