My
answer to this from a UBL/CCTS/TBG17 perspective is
that :
a)
'Year Month' could be submitted by UBL as a prospective secondary representation
term to 'date time' adding to the 'date' and 'time' secondaries which we already
have. This would enable 1) specific naming of BBIEs using this new secondary RT
and 2/ a new CCT to be defined for 'Year Month'.
b) the
new CCT would need an associated unqualified data type for 'Year
Month' to be added to the TBG17 official CCTS unqualified data type
list.
c) a
new 'qualified' data type would be added to the UBL CCT/data type schema which
would add the XSD restriction of usage of the specific XSD
primitive.
d) all
relevant UBL BBIEs could then be defined to use this new UBL data
type.
regards
Sue

xsd:gYearMonth as basis of a new datatype for credit card expiry
date?
i think stephen's question is that if we wanted
to define a data type (as the CCTS calls them) for YearMonth, can we do this
using XSD? - if so we need an NDR for its definition (stephen then suggests one
or two). the important part of this is that it allows for option day but
mandatory month and year.
which raises a maintenace question on how we
can define data types into the future. whilst the other CCTS modules are
External - i presume this one (the UBL data types) is Internal, so will we need
to add to the NDR every time we add another one?

Just a quick question for LCSC
modelling.
Would it be feasible to use xsd:gYearMonth as the base for a new
DataType (in the CCTS sense) to
cater for MM/YY (albeit YYYY-MM in ISO short date
format) as used with Credit Card expiry dates?
Thanks
