Subject: How to make \def accept block or buffer as part of (long) command argument

Hi list,
I'm playing around with blocks and buffers again, realizing that I cannot use them inbetween a \start...\stop that I defined myself. Apparently, they work between \startsection...\stopsection and the like, so I was wondering how I should define or expand #2 in the MWE below to make TeX happily accept these useful features?
Thanks a lot
Benjamin
\starttext
\let\stopMyCommand\relax
\tolerant\protected\def\startMyCommand[#1]#2\stopMyCommand{
Optional argument #1
Content #2
}
\bf Here we test the command: Works \tf
\startMyCommand[is optional]
gets processed!
\stopMyCommand
\bf Here we test the block: Works \tf
\defineblock[MyBlock]
\beginMyBlock
Block for something else.
\endMyBlock
\useblocks[MyBlock][criterium=text]
\bf Here we test the block inside command: Fails \tf
% UNCOMMENT BELOW FAILS: tex error > runaway error: end of file encountered
%
% \startMyCommand[is optional]
% Still?
%
% \beginMyBlock
% Block for something else.
% \endMyBlock
% \stopMyCommand
\definebuffer[MyBuffer]
\bf Here we test the buffer: Works \tf
\startbuffer[MyBuffer]
Buffer for something else.
\stopbuffer
\getbuffer[MyBuffer]
\bf Here we test the buffer inside command: Fails \tf
% UNCOMMENT BELOW FAILS: tex error > runaway error: end of file encountered
%
% \startMyCommand[is optional]
% Still?
%
% \startbuffer[MyBuffer]
% Buffer for something else.
% \endbuffer
% \stopMyCommand
\stoptext
