I haven't used exact files from OASIS V5.1 Standard release inside xml/5.1 directory as there were some old version numbers in catalog files. Instead I have generated fresh V5.1 from repo.
I know that situation with hosting releases on OASIS site is little bit messy, so perhaps more adjustments will be needed. Only Norm can advise.
I think that in a long term we should publish all artifacts only on docbook.org and only if needed generate duplicate files with all crazy OASIS identifiers inside them to satisfy the process.
This is at least partial fix for #78 (https://github.com/docbook/docbook/issues/78)
