 <shortdesc>Simple types are used to created derived datatypes. They provide
 a set of constraints on the value space (that is, a set of values) and the
 lexical space (that is, a set of valid literals) of a datatype.</shortdesc>

 <context><p>A simple type cannot have element content and cannot carry attributes.
 Elements that contain numbers (and strings, and dates, and so on) but do not
 contain any sub-elements are said to have a simple type.</p><p>The following
 instructions were written for the Resource perspective, but they will also
 work in many other perspectives.</p><p>To add a simple type, follow these
 steps:</p></context>
 <steps>
 <step><cmd>Open your XML schema in the XML schema editor.</cmd></step>
 <step><cmd>In the Outline view, right-click <b>Types</b>, and click <uicontrol>Add
 Simple Type</uicontrol>.</cmd></step>
 <step><cmd>In the Outline view, select the new simple type, and in the Properties
 view, click the <uicontrol>General</uicontrol> tab. Then type a new name for
 the simple type in the <uicontrol>Name</uicontrol> field.</cmd></step>
 <step><cmd>You can select the following options from the <uicontrol>Variety</uicontrol> list:</cmd>
 <choices>
 <choice><uicontrol>atomic</uicontrol>. Atomic types are all the simple types
 built into the XML schema language.</choice>
 <choice><uicontrol>list</uicontrol>. List types are comprised of sequences
 of atomic types. They have values that are comprised of finite-length sequences
 of atomic values. </choice>
 <choice><uicontrol>union</uicontrol>. A union type enables an element or attribute
 value to be one or more instances of one type drawn from the union of multiple
 atomic and list types.</choice>
 </choices>
 </step>
 <step><cmd>If you selected <uicontrol>atomic</uicontrol> from the <uicontrol>Variety</uicontrol> drop
 down list, click the <uicontrol>Browse</uicontrol> <image href="../images/Browse.gif">
 <alt>This graphic is the Browse button</alt></image> button next to the <uicontrol>Base
 type</uicontrol> field to specify a base type for the simple type.</cmd><info>The
 Set Type dialog lists all built-in and user-defined types currently available.
 You can change the <uicontrol>Scope</uicontrol> of the list by selecting one
 of the following options:<ul>
 <li><uicontrol>Workspace</uicontrol>. Lists all of the types available in
 your workspace. </li>
 <li><uicontrol>Enclosing Project</uicontrol>. Lists all of the types available

 available in your current file.</li>
 <li><uicontrol>Working Sets</uicontrol>. List all the types available within
 the selected working set.</li>
 </ul></info></step>

 down list, click the <uicontrol>Browse</uicontrol> <image href="../images/Browse.gif">

 <step><cmd>If you selected <uicontrol>union</uicontrol> from the <uicontrol>Variety</uicontrol> drop
 down list, click the <uicontrol>Browse</uicontrol> <image href="../images/Browse.gif">
 <alt>This graphic is the Browse button</alt></image> button next to the <uicontrol>Member
 types</uicontrol> field to specify the member types for the simple type.</cmd>
 <info>You can select to add both <uicontrol>Built-in simple types</uicontrol> and <uicontrol>User-defined
 simple types</uicontrol> to the member types value list. </info></step>
 <step><cmd>Click the <uicontrol>Constraints</uicontrol> tab.</cmd><info>From
 here you will be able to set specific constraint values including length constraints,
 enumerations, and patterns. </info>
 <substeps>
 <substep><cmd>Enumerations help you to define a set of valid values for simple
 types. They are the actual values the simple type can take as valid values
 in the instance document. You can either add one enumeration or several enumerations
 at a time:</cmd><info><ul>
 <li>To add one enumeration at a time, under <uicontrol>Specific constraint
 values</uicontrol>, select the <uicontrol>Enumerations</uicontrol> radio button

 <li>Select the <uicontrol>Enumerations</uicontrol> radio button.</li>
 <li>Click the <uicontrol>Add...</uicontrol> button.</li>
 <li>Enter the value of each enumeration. Each value must be separated by the <uicontrol>Delimiter
 character</uicontrol>. For example: <codeph>First, Second</codeph> will create
 two enumerations, one with the value "First" and one with the value "Second".</li>
 <li>Select the <uicontrol>Preserve leading and trailing whitespace</uicontrol> check
 box if you want any white space around your enumeration values to be preserved.
 If, for example, you select this check box, the values of <codeph>First, Second</codeph> will
 show up as "First" and " Second" (there is a space before Second) because
 you put a space before "Second" when entered the value.</li>
 <li>Click <uicontrol>OK</uicontrol>. Your enumerations will be created and
 appear in the Properties view.</li>
 </ol></li>
 </ul></info></substep>
 <substep><cmd>Patterns help you to place certain constraints regarding allowable
 values.</cmd><info>For example, you could restrict the field to only accept
 input which follows the pattern "five digits followed by two upper-case ASCII
 letters". To set a pattern constraint:<ol>
 <li>Select the <uicontrol>Patterns</uicontrol> radio button.</li>
 <li>Click the <uicontrol>Add...</uicontrol> button.</li>
 <li>Create the regular expression pattern you wish to use as your constraint
 using the <uicontrol>Regular Expression</uicontrol> wizard.</li>
 <li>Click <uicontrol>Finish</uicontrol>.</li>

 <step><cmd>Click the <uicontrol>Documentation</uicontrol> tab if you want
