For the customer schema the following table lists the corresponding post-schema-compilation properties: Table 1 In order to manipulate the schema loaded into the SOM, we should be able to traverse the SOM and get at the elements, attributes, and types stored in it.The Xml Schema class has the following properties that provide access to the collection of all global items added to the schema.Base Type Name = new Xml Qualified Name("string"," Xml Schema Max Length Facet max Length = new Xml Schema Max Length Facet(); max Length. Schema Type Name = new Xml Qualified Name("Last Name Type", " // User-defined type id Att. Schema Type = customer Type; //Create an empty schema Xml Schema cust Schema = new Xml Schema(); cust Schema. Compilation also makes the post-schema-compilation properties available.

We can use Xml Schema Simple Type List or Xml Schema Simple Type Union classes to create list or union types.
The Content property of Xml Schema Simple Type denotes whether it is a simple type restriction, list, or union.
// Create the First Name and Last Name elements Xml Schema Element first Name Elem = new Xml Schema Element(); first Name Elem. The content of elements and attributes is defined by their types.
Name = "First Name"; Xml Schema Element last Name Elem = new Xml Schema Element(); last Name Elem. Required; // The Xml Schema Use enumeration has the values // Required/Optional/Prohibited/None. To create elements or attributes whose types are one of the built-in schema types as defined in XML Schema Part 2: Datatypes, the Schema Type Name property on Xml Schema Element or Xml Schema Attribute is set with the corresponding qualified name of the type.
December 4, 2002 Priya Lakshminarayanan Despite the many articles explaining W3C XML Schema (WXS), it's not enough to discuss WXS as a specification only. SOM is a rich API which allows developers to create, edit, and validate schemas programmatically -- one of the few such tools available so far.
Educational materials should also discuss tools which aid the development of XML applications which employ WXS. SOM operates on schema documents analogously to the way DOM operates on XML documents.All the pre-schema-compilation properties can be set to change the existing values, and the schema can be re-compiled to reflect changes in the object model.The following two samples illustrate editing scenarios in the SOM.The SOM comprises an extensive set of classes corresponding to the elements in a schema. The following code creates the customer schema in memory using the SOM API.For example, the maps to Xml Schema Attribute and so on. For a complete listing of all the classes available in the System. We will use a bottom-up approach in building the schema, constructing the child elements, attributes and their corresponding types first, and then proceed to build the top-level components.// Create the simple type for the Last Name element Xml Schema Simple Type last Name Type = new Xml Schema Simple Type(); last Name Type. Content = last Name Restriction; // Associate the elements/attributes with their types first Name Elem.
