[Fritz, i did not check yesterday how huge your attachment was.

There may be an alternative, let innermost tag decide if quotes must be
removed, and outer tags do not suppress remaining quotes.  This is
performed by the patch below.
With this patch, wml rebuilds your site (i did not check if it does it
right).

I fear there are some side effects, so it needs more testing.
But if it works, there is no more problems with quotes and ePerl ;-)
