I've done a similar thing for ISO 8601:2000. Comparing
with the situation in ISO 8601:2000, I note:
many "truncated" formats starting with a hyphen
existed in ISO 8601:2000, such as -YY, -DDD,
-YYMM. All these can be confused with -CC, -CCC etc
if the minus sign and the hyphen are represented
by the same character.
this format was allowed in ISO 8601:2000 for
ordinal dates YYDDD. Similarly, YYMMDD was
allowed in ISO 8601:2000.
If one keeps in mind that both the omission of the
separator T as well as the use of more than 2 digits for
the centennial year digits require mutual agreement between
sender and recipient, then each format has at most
one interpretation that does not require such agreement.
This held true for ISO 8601:2000 and seems to be valid
for ISO 8601:2004 as well.
