/**
* The Namespaces Property Tab contains a table of namespaces in scope for the currently
* selected BPEL activity or the process. The table has the following columns:
*
* Prefix - the namespace prefix. This could be empty if the namespace was defined in
* an imported artifact (WSDL or XSD)
* Namespace - the namespace definition
* Context - the Activity or Process in which the namespace prefix was defined
* Location - the resource artifact that defines the namespace
*
* A button with the label "Assign Prefix" will be enabled if the current selection in
* the able has no namespace prefix. This will allow the user to assign a prefix.
