Correct version and revision of upstream packaged Debian package

[Tuukka Pasanen]

Hello,

After reading couple times Debian Policy documentation packaging 
conventions and especially'5.6.12.2. Special version conventions' 
chapter. I'm bit confused about revision system. As MariaDB Foundation 
wants to provide upstream packages and currently naming scheme conflicts 
when upgrading from Buster to Bullseye something should be done to solve 
situation.

Currently revision is for example: '10.6.7+maria~buster' which upgrades 
'10.6.7+maria~bullseye' which is lexical orderly lower than first one.To 
understand this bug report can be found here: 
https://jira.mariadb.org/browse/MDEV-28628 which contain more info about 
how apt works with current situation.

Thing that like to ask should revision it be more like '+maria~deb11' or 
+mariadeb11. I understood that char '~' means it's build from upstream 
version control not from official release tag. As I seek for examples 
there is packages which just add '+' chars in revision when needed extra 
stuff and then revision is just build number without .

So I like to know is there any common or tasked knowledge about how this 
can be done correctlywhich I'm no aware of? If someone can point out 
that I'm more than pleased to correct this thing.

Sincerely,
Tuukka
