Chapter 5. Writing Agent Plug-ins: Procedures
5.1. Tip: Checking XSD Annotations
There are a couple of XSD files that provide elements for agent (resource) plug-ins:
rhq-configuration.xsd and rhq-plugin.xsd.
Different properties and attributes are defined in these schema files. They are annotated so you can see what the existing, default schema makes available.
For example, for the subCategory attribute:
<xs:attribute name="subCategory" use="optional">
<xs:annotation>
<xs:documentation>
Resource types can be grouped into subcategories. A subcategory
defines "like" resource types so they can, for example, be shown together
in a UI group tab. You can, therefore, define multiple resource types
and group them together by making their subCategory attributes the same.
</xs:documentation>
</xs:annotation>
</xs:attribute>
Read through the annotations in the XSD files to help plan what your plug-in will do and determine whether your configuration requires custom schema.
