This extension point is used to contribute value-add's. Each value-add contribution must be bound via the "org.eclipse.tcf.te.tcf.core.bindings" extenions point. Multiple bindings for the same value-add are cumulative. Declares a value-add contribution. The unique id of the value-add contribution. The label representing the value-add within the UI. The class that implements <code>org.eclipse.tcf.te.tcf.core.va.interfaces.IValueAdd</code> or extends <code>org.eclipse.tcf.te.tcf.core.va.AbstractValueAdd</code>. <p> The value-add implementation class must be specified either by the class attribute or the class child element! If set to "true", than it marks the value-add as optional. Optional value-add are silently ignored if the necessary executable is not present or the launch of such value-add is failing. If not set, the attribute does default to "false". A short description of the value-add to be presented in the UI. Used when creating an <code>IExecutableExtension</code> with a named parameter, or more than one. The class that implements <code>org.eclipse.tcf.te.tcf.core.va.interfaces.IValueAdd</code> or extends <code>org.eclipse.tcf.te.tcf.core.va.AbstractValueAdd</code>. <p> The value-add implementation class must be specified either by the class attribute or the class child element! A parameter for an <code>IExecutableExtension</code>. <p>The parameter name.</p> <p>The parameter value.</p> Target Explorer 1.0.0 This is an example of the extension point usage: <p> <pre><code> <extension point="org.eclipse.tcf.te.tcf.core.valueadds"> <valueadd id="org.eclipse.tcf.te.tcf.core.valueadd.myValueAdd" class="org.eclipse.tcf.te.tcf.core.valueadd.MyValueAddImpl"> </valueadd> </extension> </code></pre> The provider of a value-add must implement <samp>org.eclipse.tcf.te.tcf.core.va.interfaces.IValueAdd</samp>.
