Bruce,

The ID attribute on the mods element should probably not be used for any
"descriptive" identifier.  That information really belongs in the
identifier or recordIdentifier elements.  The ID attributes sprinkled
throughout the schema, which are included on the elements mods,
titleInfo, name, subject, and relatedItem, allow implementors to link to
specific parts of the record by using the XML ID/IDREFS data types.  The
use of mods in the context of a METS document drove the inclusion of
these attributes.  Below is an abbreviated METS document to illustrate
the linking from the structmap section of the METS document into the
mods record.  The bolded attribute values demonstrate the links.
