<div><p>Validating a DTD file lets you verify that it is well formed and
does not contain any errors.</p>
<div class="section"><p>The following instructions were written for the Resource perspective,
but they will also work in many other perspectives. </p>
<p>To validate
a DTD, follow these steps:</p>
</div>
<div class="p"><span>In the Navigator view, right-click the DTD and click <span class="menucascade">
<span class="uicontrol">Validate DTD File</span></span>.</span></div>
<div class="section">A dialog opens, indicating if the DTD file was successfully validated
or not. If the file is invalid, any errors will appear in the Problems view.  <p><strong>Note</strong>:
If you receive an error message indicating that the Problems view is full,
you can increase the number of error messages allowed by selecting <span class="menucascade">
<span class="uicontrol">Properties</span> &gt; <span class="uicontrol">Validation</span></span> from
the project's pop-up menu and specifying the maximum number of error messages
allowed. You might have to select the <span class="uicontrol">Override validation preferences</span> check
box in order to enable the <span class="uicontrol">Maximum number of validation messages</span> field</p>
<p>You
can set up project's properties so that different types of project resources
are automatically validated when you save them. From a project's pop-up menu
select <span class="uicontrol">Properties</span>, then select <span class="uicontrol">Validation</span>.
Any validators you can run against your project will be listed in the
Validation page. </p>
