parameter ID=WLC (user profile)

[Michael Marten]

Hello,
I just detected - if I view my user profile , tab "Parameters" -
that there exists an entry "WLC" or "SWA".
 
Parameter ID          value                short text
--------------------         ---------------
----------------------------------------------
WLC                         XXX X X  X       Workflow: User-specific
settings
SWA                         -                          Workflow: Container
debugging status
 
What is the purpose?
Are there other workflow related entries?
Any documentation?
Michael
