What is the use of allowing variablelists within variablelists?

[Stefan Knorr <sknorr@suse.de>]

Hi all,

Tom (CCd) and I were wondering about a quirk (?) in the DocBook 5 
schema:
What is the rationale for allowing the following construct?

 <variablelist>
   <variablelist>
 [...]

(The same works for other kinds of lists within variablelist.)

Regards,

Stefan.
