According to the tag library, <origination> is comparable to MARC fields 
100, 110, 700, and 710. Is there a best practice for the number of 
creators to include in <origination> at the <archdesc> level?

Most of our collections have a single creator, which we tag within 
<origination> using either <persname>, <corpname>, or <famname> with the 
appropriate value in the encodinganalog, either 100 or 110.

However, some of our collections have multiple creators, which it would 
be possible for us to include in <origination>, tagging them as either 
<persname>, <corpname>, or <famname> with the appropriate encoding 
attribute, either 100, 110, 700, or 710.

Would it be best practice to include the main authors and /all/ 
additional authors, or only the main author (corresponding to the 100 or 
110 field in the MARC record)?

Thanks for the feedback.
