Study Subject
The use of the openContent element in the schema below was part of trying to
determine how XHTML5 and XML could work together. If the XSD 1.1 openContent
element were usable in XML and XHTML5, it would aid the development of
combined implementations.
Bug: XSD 1.1 openContent mode="interleave in XML Page
Unfortunately, the XML page that was generated by an XSD1.1 schema shown
below was incorrect.
The schema below, which includes an openContent element successfully
validated
“SystemID: D:\XML\Schema\Schema1_1\interleave\books.xsd
Main validation file: D:\XML\Schema\Schema1_1\interleave\books.xsd
Engine name: Saxon-EE 9.3.0.5
Severity: info
Description: Validation successful.
<?xml version="1.0" encoding="UTF-8"?>”
The test case is based upon slides 266 and 217 of XML Schema 1.1 by Roger L.
Costello, (http://www.xfront.com) dated 24 March 2011. Slide 217 is a
complete XML page.
http://www.xfront.com/files/tutorials.html
Then pressing xml schema 1.1. This is followed by going “XML Schema 1.1
Tutorial”
And then going to the hyperlink labeled
Here is the tutorial: XML Schema 1.1 (PowerPoint document). It appears that
there are at least two versions with different dates and slide numbers of
this PowerPoint presentation that can be found with a Google search.
XSD1.1 Schema
</xs:schema> <?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
targetNamespace="http://www.books.org" xmlns="http://www.books.org"
elementFormDefault="qualified">
<xs:element name="Book">
<xs:complexType>
<xs:openContent mode="interleave">
<xs:any namespace="http://www.r.org"
processContents="strict"/>
</xs:openContent>
<xs:sequence>
<xs:element name="Title" type="xs:string"/>
<xs:element name="Author" type="xs:string"/>
<xs:element name="Date" type="xs:string"/>
<xs:element name="ISBN" type="xs:string"/>
<xs:element name="Publisher" type="xs:string"/>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
When I attempted to use Tools.Generate XML schema, I received the following
error message.
Description: cid:
I ignored the error and generated:
<?xml version="1.0" encoding="UTF-8"?>
<Book xmlns="http://www.books.org"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.books.org
file:/D:/XML/Schema/Schema1_1/interleave/books.xsd
<http://www.books.org%20file:/D:/XML/Schema/Schema1_1/interleave/books.xsd>
">
</Book>
If I comment out
<!--xs:openContent mode="interleave">
<xs:any namespace="http://www.r.org"
processContents="strict"/>
</xs:openContent-->
I was able to generate:
<?xml version="1.0" encoding="UTF-8"?>
<Book xmlns="http://www.books.org"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.books.org
file:/D:/XML/Schema/Schema1_1/interleave/books.xsd">
<Title>Title0</Title>
<Author>Author0</Author>
<Date>Date0</Date>
<ISBN>ISBN0</ISBN>
<Publisher>Publisher0</Publisher>
</Book>
The result with the above XML page was:

I created an r.xsd schema based on the XML page shown in :
