Okay, I understand the problem now, but I still hate the syntax.
Wouldn't it be better to completely change the syntax of <ifeq> like
this:

<ifeq this="0" that="0">
  <then>
     foo
  </then>
  <else
     bar
  </else>
</ifeq>

The <else> tag is optional.  This looks much more like HTML and it
should be easier to cascade multiple <ifeq> constructs.  Similar
syntax for <ifneq> and <if> (the latter seems to be near to the <when>
tag).

I don't know, whether this can be easily implemented, but it sounds
much more intuitive to use to me than the cascading of quotes and
quoted quotes.  Instead of this we have a syntax similar to the
<table> tag here.

Tschoeeee
