the initializeforbuilding(), compilequery() and addbinding() methods may not be called after generateresults() has been called until the builder indicates that the generated output is being removed by calling the done() method.

for the nsidomdocumentxbl interface's nsidomdocumentxbl.addbinding() and nsidomdocumentxbl.loadbindingdocument() methods, the originating principal is the one of the script making the call, or the principal of the document the call is made on if there isn't a script.

note: some older papers mentioned dom methods document.addbinding and document.removebinding; these were subsequently discarded as redundant and not implemented.

this situation can occur when bindings implicitly inherit, e.g., through the use of addbinding.

each of these declared bindings must be supplied to the query processor via its addbinding() method.
