I'm aware that domain IDs in a fabric can have values between 1-253.
However in scalability matrix for either FOS 7.x or 8.x , maximum value for domain IDs is 56.
Does anybody know where this limitation come from?

The maximum value of 56 listed in the scalability matrix the maximum number of supported switches in a fabric (with a certain FOS code, product family etc), and not the largest number which can be used for as domain id....
The number is the tested limit - for a stable fabric - of switch interconnected (with certain FOS version, type and interconnectons).

Thanks Martin! I see same figure for both FOS 7.x and 8.x regardless of platform Brocade DCX 8510 / X6
So 56 domain IDs is the maximum safe number to have in a fabric as it was tested - but would there be scenarious where more would be permitted? Is there a process where Broadcom would validate environments where more could be allowed? Thinking of environments with a few DCXs and lots of 24/48 port switches i native mode (overall under the 6.000 ports limit)
