Editing existing references

When existing XML is edited, bibItem references may be amended, inserted, or deleted in the original document. Where bibItems change their target, they must be replaced and receive a new ID. Where they are amended but refer to the same target they must retain their ID.

It is vitally important that:

bibItems that are amended but still refer to the same target MUST be treated as the same bibItem (for instance when the name changes). These bibItems must retain their id value, and a confirmation value of deferred.
bibItems that are amended to refer to a different target MUST be treated as a new bibItem (a deletion then insertion). These bibItems require a new id. Note that referring to a different section of the same document counts as a different target.

As always, id attributes must not be re-used, even if they are deleted.

When updating Law content:

first, mark all existing legal bibItem elements and legal extracts with confirmation="deferred"
when the bibItem target is unchanged, this reference should not be amended further, including retaining the existing id.
when the bibItem refers to a different target, use a new and previously unused id (as above) and remove the inserted confirmation="deferred" .

Please note that these rules do not apply to bibItems that occur within citeGrp.
