Manuscripts contain identifiable items, usually physically tied to a locus. Note that a <msItem> is not the same as a bibliographic item.

• <locus>, if present, must be given first
• then any of the following, in a specified order:
  • <author>, <respStmt>
  • <title>, <rubric>, <incipit>, <explicit>, <colophon>
  • <q>, <textLang>, <decoNote>, <bibl>, <listBibl>, <note>
  • ... or nested <msItem>s
