nsIXULTemplateBuilder Interface

 Add a listener to this template builder. The template builder
 holds a strong reference to the listener.

void addListener(in nsIXULBuilderListener aListener)

 Invoked lazily by a XUL element that needs its child content
 built.

[noscript] void createContents(in nsIContent_ptr aElement)

 Called to initialize a XUL content builder on a particular root
 element. This element presumably has a ``datasources''
 attribute, which the builder will parse to set up the template
 builder's datasources.

[noscript] void init(in nsIContent_ptr aElement)

 Force the template builder to rebuild its content.

void rebuild()

 Reload any of our RDF datasources that support nsIRDFRemoteDatasource. 

 @note This is a temporary hack so that remote-XUL authors can
       reload remote datasources. When RDF becomes remote-scriptable,
       this will no longer be necessary.

void refresh()

 Remove a listener from this template builder.

void removeListener(in nsIXULBuilderListener aListener)
