Face: Mandatory / optional fields

[a-machado-ipsg]

Why fields like
10/PAS[10.023]Photo Acquisition Source
10/SXS[10.026]Subject Facial Description
10/SEC[10.027]Subject Eye Color
10/SHC[10.028]Subject Hair Color
should be mandatory if 10/SAP[10.013]Subject Acquisition Profile >= 40?

Question to be raised to Facial WG and NIST. To avoid to have too much mandatory fields.
