<context><p>The following instructions were written for the Resource perspective, | |
but they will also work in many other perspectives.</p><p>To validate an XML | |
schema:</p></context> | |
<steps> | |
<step><cmd>Right-click your file in the Navigator view and click <uicontrol>Run | |
Validation</uicontrol>.</cmd></step> | |
<step><cmd> If validation was not successful, you can refer to the Problems | |
view to see what problems were logged. </cmd><info> <note>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 | |
> Validation</uicontrol></menucascade> <?Pub Caret?>and specifying the maximum | |
number of error messages allowed.</note></info></step> | |
</steps> | |
<result><p>The XML schema support in the XML schema editor is based on the | |
W3C XML Schema Recommendation Specification. The XML Schema specifications | |
XML Schema Part 1: Structures and XML Schema Part 2: Datatypes from the W3C | |
Web site are used for validation.</p><p>Certain error messages contain a reference | |
to the schema constraints listed in Appendix C of the XML Schema Part 1: Structures | |
document. Each constraint has a unique name that will be referenced in the | |
error message. For example, if you receive an error message with this text: | |
<systemoutput>ct-props-correct</systemoutput> and you searched in the Structure | |
document for the text, you would find that it is for the section "Schema Component | |
Constraint: Complex Type Definition Properties Correct". </p><p>You can set | |
up a 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 project will be listed in the Validation page.</p></result> | |
