ECF 4.01 Errata 2 ?
ECF v 4.01 os makes UBL 2.1 prd2 normative.
For those you have not yet mastered to OASIS coding scheme, ‘os’ = “OASIS Standard” and’prd2’ = “Public Review Draft 02”.
In other words, to conform to the ECF OASIS standard, you must use UBL that is not an OASIS standard.
No need for alarm, UBL 2.1 is now an OASIS Standard (i.e. os) and the little bit of UBL used by ECF is not revised in the UBL v2.1 os.
But here is the problem; to be conformant to ECF v4.01 plus Errata 01 you must use UBL v2.1 prd2 – so just exactly where do ECF implementers go to get UBL 2.1 prd2?
If you go to the UBL web site in OASIS you can get UBL v2.1 os, but are not provided with any way of finding UBL v2.1 prd2.
For those with arcane knowledge of OASIS, one might try:
http://docs.oasis-open.org/ubl/prd2-UBL-2.1/
This will deliver you to:
Presumably UBL-2.1-PRD2-2011-05-30.zip is the ECF v4.01 os plus Errata 01 compliant version (however this was not the name of the zip file at the time this was available for public review).
In the future the ECF TC may want to consider a policy of only building on approved standards. But for now the TC may want to consider a second Errata (i.e. Errata 02) to ECF 4.01 os plus Errata 01 to make UBL 2.1 os normative instead of UBL 2.1 prd2.
