Enhanced Enumeration?

[Richard Rascher-Friesenhausen <richard@mevis.de>]

Hello,

i'm currently writing a script on biosignal analysis. And therefore i need 
such things as definitions, lemmas, theorems, remarks and so on. One can 
easily define numbered versions of these using \defineenumeration. But i need 
two extra fetures:

first: Some theorems have names, some not. Is it possible to introduce a new 
optional argument to the enumeration (a 'named enumeration')? Something like

  \startTheorem[Shannon Sampling Theorem]
    You have to select $f_s\ge2 f_h$.
  \stopTheorem

to get

  Theorem 1.1: (Shannon Sampling Theorem)
     You have top select fs\ge fh.

Nevertheless it should be possible to label the theorem:

  \startTheorem[thm:shannon][Shannon Sampling Theorem]
    You have to select $f_s\ge2 f_h$.
  \stopTheorem

  \in{Theorem}[thm:shannon] we have seen....


Second: Is it possible to generate a content list of all named theorems?

Thanks a lot in advance
