[texhax] tikz vs. expl3

[Arno Trautmann]

Hi all,

I am trying to write a small package with some special drawing 
instructions. Inspired by the articles by Joseph Wright, I am using 
expl3 and xparse. Now I have problems using expl3-Syntax together with 
tikz-instructions: tikz needs explicit spaces (no problem with 
\ExplSyntaxNames) and explicit colons as in [domain=1:3].

So my question: how to handle the colon in the domain-value? I don’t 
want to fall back on l2ε syntax in my code at this position … is there 
any way to tell tikz inside an expl3-code to recognize a colon?

cheers
Arno
