:Again you're missing the fact that there are at least different
:Text subsystems within Oberon System 3.  You are also ignoring
:the fact that from the "ETH" viewpoint there is also HTML and
XML.  You can hate HTML and XML all you want, but I wouldn't
:be surprised if ETH eventually dropped support for S3 text
:altogether.  Remember the user interface for AOS is built on
:XML.  Also the "V4 Texts importer" is not really that good.
:(Read barely useable and only for the simplist of V4 texts.)
------------------------

Q1.  Is XML essential to AOS ?

Q2.  Is  AOS usable yet ? 
   eg. post and fetch email and news.

Q3. The description of V4's 'folding' facility sounds powerfull
   eg. to make the analysis of existing src-code managable;
    Does this make sense, or are there hidden problems ?

Q4. Apparently I can read V4 code from S3 (I think I've done it);
    but can I use the folding facility while running S3 ?
   I suspect not.

Q5. Perhaps there are other mechanisms in S3 (I'm only familiar with
      a small frcation of the facilities) can make substantial documentation
      and comments available, but selectively hidden as required, in the
      compilable source code ?
