German hyphenation patterns

["Thomas A. Schmitz" <thomas.schmitz@uni-bonn.de>]

All,

German orthography is a mess right now, we now have two sets of  
rules, old and new. New hyphenation is ugly and rules are constantly  
changing. I see that ConTeXt has lang-deo.pat, so I was hoping that  
this would produce "old" patterns, but it doesn't seem to work:

\enableregime[utf]
\mainlanguage[deo]

\starttext

\showhyphens{gestorben}

\showhyphens{Bierdeckel}

\showhyphens{äußerst}

\stoptext

gives me:

Underfull \hbox (badness 10000) in paragraph at lines 8--8
[] \*10ptrmtf* ge-stor-ben

Underfull \hbox (badness 10000) in paragraph at lines 10--10
[] \*10ptrmtf* Bier-de-ckel

Underfull \hbox (badness 10000) in paragraph at lines 12--12
[] \*10ptrmtf* ‰u-ˇerst

which is identical to \mainlanguage[de]. Patterns should be Bierdek- 
kel and ‰us-serst. Am I missing something, how can I enable "old"  
patterns?

Thanks

Thomas
