9.  Part Description

<msPart>

The <msPart> element contains the description (intellectual, physical and historical) of a manuscript or manuscript fragment that shares the binding with another manuscript but that is of separate origin.

Since the <msPart> element is intended to catalogue multiple separate manuscripts that are bound together, or exist together, or share the same call number, its functions and attributes are in the main the same as those of <msDescription>.  It is a mechanism that allows the cataloguer to retain the top level of identity (<msIdentifier>), but to branch out thereafter into as many parts, or even subparts, as necessary.

Specific to <msPart> (as opposed to the direct subelements of msDescription) are only two elements:  <head> and <idno>.  The <head> element creates the space for the guiding statements used by the cataloguer to warn or instruct the user:  "this is Part N. 1" or "this is the winter section of the multi-volume breviary" or "this is the flyleaf."  The <idno> element allows the cataloguer to report various call numbers if the parts are in fact separately numbered by the holding institution.

Note:  <msDescription> must contain <msIdentifier> (embodied in any one of its subelements, including <idno>; <msPart> may contain <idno>.

Other than the four global attributes, <msPart> has four additional attributes:  "status" (with values as frag; def; unk);  "composite" (with values as y; n; u); dateAttrib (with values as dated; datable; unknown); there is no default value for any of these.  The fourth attribute shared by <msDescription> and <msPart> is the crucial "type" attribute; it is expected that this will be used with some frequency in the configuration 'type="dipl"' to signal the parts of a manuscript that are diplomatic or archival in nature.
