[cisco-voip] CSF Device name and format - Discrepancy between older docs, online help and reality - CUCM 10.5.2

[Brian V]

I have a customer where the username has a dot "." in it.  First.Last
Cisco's docs recommend to make the CSF device name be CSF + Username.
I know this is not required anymore but many customers like the consistency
of that naming standard.
On my current customers CUCM 10.5.2.10000-5 when i try to add a CSF device
with a dot I get the error message that the device name should contain the
valid characters [a-zA-Z0-9]{1,15}  which seems to imply it can only be 15
characters long and contain letters and numbers only

On my current customers CUCM 10.5.2.10000-5 server the online help says
that CSF devices can contain the following:   "Enter a text name for the
Client Services Framework. This name can comprise up to 50 characters.
Valid characters include letters, numbers, dashes, dots (periods), spaces,
and underscores."

CSF doc for 9.x says the same thing that dot, dash, underscore and
length=50 is ok

CSF doc for jabber 10.6 doesn't mention any requirements for the name but
does recommend using CSF+Username as the format.

There is a support community posting about this referencing a bug that
states it wont be fixed.

https://tools.cisco.com/bugsearch/bug/CSCus90842/?reffering_site=dumpcr

So is there a documentation bug or did Cisco change the rules somewhere
along the way ?

Is there any definitive documentation that states the proper naming
standard for the CSF device and the other Jabber device types (BOT, TCT,
TAB)
