<context><p>The following instructions were written for the Resource perspective,
but they will also work in many other perspectives.&nbsp;</p><p>To validate
a DTD, follow these steps:</p></context>
<steps>
<step><cmd>In the Navigator view, right-click the DTD and click <menucascade>
<uicontrol>Validate DTD File</uicontrol></menucascade>.</cmd></step>
</steps>
<result>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. &nbsp;<p><b>Note</b>:
If you receive an error message indicating that the Problems view is full,
you can increase the number of error messages allowed by selecting <menucascade>
<uicontrol>Properties</uicontrol><uicontrol>Validation</uicontrol></menucascade> from
the project's pop-up menu and specifying the maximum number of error messages
allowed. You might have to select the <uicontrol>Override validation preferences</uicontrol> check
box in order to enable the <uicontrol>Maximum number of validation messages</uicontrol> 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 <uicontrol>Properties</uicontrol>, then select <uicontrol>Validation</uicontrol>.
Any validators you can run against your&nbsp;project will be listed in the
Validation page.&nbsp;</p></result>
