Bridgehead alternatives

[Kate.Wringe@sybase.com]

Currently we use docbook 4.2 to document
software. We have multiple bridgeheads within sect1s, sect2s, sect3s, and
sect4s.
We use the bridgeheads to add titles
within a sect. 

For example: in a sect1, we use bridgeheads
to divide up the text:
STATEMENTNAME (sect1)
Syntax (bridgehead)
Parmeters (bridgehead)
Remarks (bridgehead)
See also (bridgehead)
Examples (bridgehead)

We'd like to replace the bridgeheads
with a block tag (preferrably a floating one)  that would contain
a title tag followed by para tags, procedure tags, programlisting tags,
orderedlists, etc.

The closest tag I've found is simplesect.
However, if I use a simplesect within a sect,  then I can't 
add a nested sect after the simplesect.
For example, I'd like to be able to do the following:
<sect1>
...
<simplesect><title>Syntax
</title>
<para>....</para>
....
</simplesect>
        <sect2>
         
      ....
        </sect2>
        <sect2>
         
      ...
        </sect2>
</sect1>

Any suggestions?

Thank you!
