=== Reference modification: convert to all parts reference

In ISO, an All Parts reference is a reference to all parts of a standard. If a standard consists of parts,
only those parts are referenced in the ISO web site (as retrieved by the isobib gem). A part reference is
converted to an All Parts reference by making the part reference a partOf relation to a new reference,
which strips the part number and part title of the original, and its abstract. The operation is destructive.

=== Reference modification: convert to most recent reference

In ISO, an undated reference is interpreted as a _de dicto_ reference to the most recent instance of the
reference; if the document is read after a new version of the reference has been issued, the reference is taken
to refer to that new instance, even if that instance had not been published at the time the bibliography was authored.
All references on the ISO web site (as retrieved by the isobib gem) are dated. A dated reference is
converted to a Most Recent referece by making the dated reference an instance relation to a new reference,
which strips the date of publication of the original, and its abstract. The operation is destructive.
