Jeffrey Zhong commented on HBASE-10183:
---------------------------------------
Hey,
[~ram_krish], [~anoop.hbase] Do you guys want to take this? Let's just document
that [0,31] is our reserved tag value range so a user should not use them
otherwise they may collide with future Hbase implementations. I can't think a
good way to enforce this by code.
Thanks.

> If we don't reserve a system tag types now, let's say 0-64(total tag type
> range is 0-255). We'll have a hard time when introducing a new system tag
> type in the future because the new tag type may collide with an existing user
> tag type as tag is open to users as well.
> [~ram_krish], [~anoop.hbase] How do you guys think?
> Thanks!
