1. The

1. the

    to represent the same

   Gloss
   t (sufficiently defined)

    or a similar though less specific

1. meaning 

   Gloss
   t (primitive)

2. Other requirements similar for those applicable to mapping may also apply including:
   1. An indication of the degree of correlation between

1. 1. the  

      Gloss

       and the SNOMED CT expression.
   2. An indication of whether

1. 1. the 

      Gloss
      t other-code t: other-codes

       was created before any single concept representation of that meaning in SNOMED CT or whether the single concept representation in SNOMED CT predated the creation of the association.
