[dev-context] Namespace for users

[Wolfgang Schuster]

Hi Hans and all others.

Is it possible to add a command to allow users to
define their own namespace for commands and modules to avoid problems
with macros in the core.

I would suggest to use i slightly modified version of the
\definesystemvariable command.

\def\????prefix  {????}
\def\@@@@prefix  {@@@@}

\def\defineuservariable#1{\setevalue{\????prefix#1}{\@@@@prefix#1}}

Another question how many letters should we use for our prefixes.

Two avoid problems with other users we should use a combination of a
user prefix 'xx' (e.g. ws (two letters) or wolf (four letters) for me)
and a command prefix 'yy' as already used by ConTeXt (e.g. sf for
SpeciFics).

--> \defineuservariable{xxyy} or \defineuservariable{xxxxyy}

What do you think about my idea.

Wolfgang
