XQuery (O'Reilly Media, ). Schemas evolve over time, and it is useful to be able to automatically.

Listing 1. Listing 2. This technique works where a static list exists but new items are added on an ongoing basis. The creation of the data can be slightly more complicated, but maintaining the schema and related applications is greatly simplified. Of course, this data could manage all color information in an attribute instead of an element. Modular schema assembly You might modularize schemas for a lot of reasons, but this section focuses on using modularity to extend them. In short, creating several schema modules and including them into your base schema is a form of extending the base schema.

Generic elements

Listing 3. Listing 4.

Listing 5. Because the example in Listing 5 uses only one namespace, element and attribute names must be unique in the combined resolved form. Also, the occurrence rules must be consistent in the resolved form.

Although adding modules is a form of extending a schema, the potential for building a set of dynamically assembled modules to create flexible schemas for different environments and applications is a powerful concept for optimizing development and maintenance effort.

You can create a library of predefined, consistent declarations for developers to selectively use throughout the enterprise.

Even so, take special care to prevent naming collisions and other errors from occurring, especially in a single namespace. Abstract elements and substitution groups The W3C XML Schema allows for a class of element types that generally appear in the same locations to be treated as a group of equivalent elements in type definitions. For example, you might have several types of named objects that is, people, places, things that appear in text as inline elements, including person, city, lodging, restaurant, and museum.

Listing 6. This means that all elements that are members of the substitution group that has the name of an another element can be placed wherever that element is allowed or an abstract element can serve this purpose. The data instance in Listing 7 is valid with this schema and its substitution group extensions. You can also use this technique with substitutions that reference an abstract element. Listing 7. It defines a simple code list with the element type color, which contains four possible elements, the first three of which are given known color names.

The last element in the group is sometimes called a generic element and is designed to allow any value to be inserted in the name attribute, thereby allowing you to add new colors to the list as needed over time.

Listing 6. This means that all elements that are members of the substitution group that has the name of an another element can be placed wherever that element is allowed or an abstract element can serve this purpose.

The data instance in Listing 7 is valid with this schema and its substitution group extensions. PDF and XPS format are mostly dedicated to printing, and may be generated from DocBook or textinfo files, and should not be used as source files.

PDF it less convenient for the web, because not all search engines can parse the content. Tex, even it is rather old, does not have very simple tools to process it.

Texinfo also requires a tedious manual editing. Texinfo can be - theoretically - converted to DocBook by makeinfo.

But the interest of DocBook is in separating data and presenting, the possibility to create automatically documents, and the ability to generate documents from databases.Modular schema assembly You might modularize schemas for a lot of reasons, but this section focuses on using modularity to extend them. Extension to an existing type The W3C XML Schema lets you extend existing type definitions to add additional sub-elements, adding additional elements to the data model's structure.

For example, suppose you misspell the name of an element, or you assume that a child element can only appear once, when the schema says it can be repeating.

It might have been nice if they had published a simpler XQuery 1. Listing 6. IBM product evaluation versions : Get your hands on application development tools and middleware products. What makes this example extensible is that the schema developer only has to add a new element declaration indicating that it is a member of the substitution group.

This makes it difficult to reason about schemas, for example to prove that a modification to a schema is backwards compatible.

A schema document may include other schema documents for the same namespace, and may import schema documents for a different namespace.
