+This example shows how to use ordered types to capture and maintain
+element order, including element wildcards.
+
+The example consists of the following files:
+
+transactions.xsd
+ XML Schema which describes various bank transactions. A batch of
+ transactions can contain any number of different transactions in
+ any order but the order of transaction in the batch is significant.
+
+library.xml
+ Sample XML instance document.
+
+transactions.hxx
+transactions.cxx
+ C++ types that represent the given vocabulary as well as a set of
+ parsing and serialization functions. These are generated by XSD
+ from transactions.xsd. Note that the --ordered-type option is
+ used to indicate to the XSD compiler that the batch type is
+ ordered. We also use the --generate-wildcard option to enable
+ wildcard support. An element wildcard is used in the batch to
+ allow transaction extensions.
+
+driver.cxx
+ Driver for the example. It first calls one of the parsing functions
+ that constructs the object model from the input XML file. It then
+ iterates over transactions in the batch using the content order
+ sequence. The driver then performs various modifications of the
+ object model while showing how to maintain the content order.
+ Finally, it saves the modified transaction batch back to XML to
+ verify that the content order is preserved in the output document.
+
+To run the example on the sample XML instance document simply execute:
+
+$ ./driver transactions.xml

+This example shows how to use ordered types to capture mixed content
+text and to maintain order information between elements and text.
+
+In this example we use mixed content model to describe text with
+embedded links in the form:
+
+ This paragraph talks about <a href="uri">time</a>.
+
+The example transforms such text into plain text with references in
+the form:
+
+ This paragraph talks about time[uri].
+
+It also saves the modified text back to XML in order to verify the
+element and text order.
+
+The example consists of the following files:
+
+text.xsd
+ XML Schema which describes "text with links" instance documents.
+
+text.xml
+ Sample XML instance document.
+
+text.hxx
+text.cxx
+ C++ types that represent the given vocabulary as well as a set of
+ parsing and serialization functions. These are generated by XSD
+ from text.xsd. Note that the --ordered-type-mixed option is used
+ to indicate to the XSD compiler that all types with mixed content
+ should be automatically treated as ordered.
+
+driver.cxx
+ Driver for the example. It first calls one of the parsing functions
+ that constructs the object model from the input XML file. It then
+ iterates over the text and elements in the content order to convert
+ the document to its plain text representation. The driver then adds
+ another paragraph of text and a link to the object model while showing
+ how to maintain the content order. Finally, it saves the modified
+ text back to XML to verify that the content order is preserved in
+ the output document.
+
+To run the example on the sample XML instance document simply execute:
+
+$ ./driver text.xml
