helpKey Properties Files Extension

Each plug-in that contributes helpKey properties files must declare an extension to org.eclipse.datatools.help.helpKeyProperties in its plug-in manifest (plugin.xml file).

For example:
    <extension point="org.eclipse.datatools.help.helpKeyProperties">
        <contextIds plugin="org.eclipse.datatools.connectivity.ui"
            file="org.eclipse.datatools.connectivity.ui.contextIds.properties"/>
        <searchExpressions plugin="org.eclipse.datatools.connectivity.ui"
            file="org.eclipse.datatools.connectivity.ui.searchExpressions.properties"/>
    </extension>

The <contextIds> element identifies a helpKey properties file that defines help context IDs, and the UI plug-in for which it is provided.

The <searchExpressions> element identifies a helpKey properties file that defines context-specific help search expressions, and the UI plug-in for which it is provided.

To accommodate context-sensitive help plug-ins that serve more than one UI plug-in, the <extension> element can contain any number of <contextIds> and <searchExpressions> elements.
