In we globally specify the qualification of elements and attributes by setting the values of both elementFormDefault and attributeFormDefault to unqualified. Strictly speaking, these settings are unnecessary because the values are the defaults for the two attributes we make them here to highlight the contrast between this case and other cases we describe later.
We can achieve a similar but not identical outcome by declaring an element in a schema, and by setting the element's content appropriately:

As XML schemas become more widespread, schema authors will want to create simple and complex types that can be shared and used as building blocks for creating new schemas. XML Schemas already provides types that play this role, in particular, the types described in the Simple Types appendix and in an introductory type library.
This declaration references an existing element, comment , that was declared elsewhere in the purchase order schema. In general, the value of the ref attribute must reference a global element, . one that has been declared under schema rather than as part of a complex type definition. The consequence of this declaration is that an element called comment may appear in an instance document, and its content must be consistent with that element's type, in this case, string .
In this case, a schema processor will process two elements, a city element, and an eacute element for the contents of which the processor will supply the single character xe9 . Note that the extra element will complicate string matching the two forms of the name Montr xe9 al given in the two examples above will not match each other using normal string-comparison techniques.
Like the other free text versions, the Google Books one will be time-limted: one month. (The audiobook versions are the only ones that will remain free forever).
The complex types in the instance document, and some of the simple types, are defined in the schema for purchase orders. The other simple types are defined as part of XML Schema's repertoire of built-in simple types.
Note that it is possible to derive a list type from the atomic type string . However, a string may contain white space, and white space delimits the items in a list type, so you should be careful using list types whose base type is string . For example, suppose we have defined a list type with a length facet equal to 8, and base type string , then the following 8 item list is legal:
When a complex type is derived by extension, its effective content model is the content model of the base type plus the content model specified in the type derivation. Furthermore, the two content models are treated as two children of a sequential group. In the case of UKAddress , the content model of UKAddress is the content model of Address plus the declarations for a postcode element and an exportCode attribute. This is like defining the UKAddress from scratch as follows:
