Seems like a great improvement.  I'm in favor.

(Wearing my RNG geek hat)

Czech proposed to replace 

sml_CT_CalcCell =
  attribute r { sml_ST_CellRef }?,
  attribute ref { sml_ST_CellRef }?,

by 

sml_CT_CalcCell =
(attribute r { sml_ST_CellRef } |
attribute ref { sml_ST_CellRef }), 

since either @r or @ref is required but not both.

I believe that this makes perfect sense.  Note that the OOXML RELAX NG schemas are sometimes more strict than the OOXML XSD schemas already (e.g., root elements).

Cheers,
Makoto
