DOCBOOK: command description: arg and option

["Fischer, Oliver" <plexus at snafu dot de>]

Hello,

I don't get the difference between arg and option. OK, according 
to the dtd. The syntactial difference is clear, but not the 
semantical one.

If I describe, I can use <arg> for -a or -dontkillit and so one. 
But why can I use option als child of arg?
And why can't I use <arg> within <para> as <option>?

My concrete situation is, that I described a command with 
cmdsynopsis, using <arg> for all the options as -file and so on. 
But within the text I must use option if I write something as:

Use the <option>-file</option> to specify an file...

Thanks,

Oliver
