    and sir  what are transparent layers, and how can i use them.

Instead of setting a background colour in the mapnik style sheet, you
can set it to transparent, then you just do a limited subset, then
load it as a non-base layer in openlayers
You can see one here:
<http://svn.toolserver.org/svnroot/mazder/styles/surveillance/common.xml>

and see it in action here:
<http://toolserver.org/~osm/styles/?zoom=2&lat=0&lon=0&layers=B000T0FF0000F0FFF>
