DOCBOOK-APPS: how to upgrade docbook XSL stylesheets?

["Robert P. J. Day" <rpjday@mindspring.com>]

  is there anything to upgrading to a newer set of docbook
XSL stylesheets besides just downloading the tarball and 
installing it in the right place?  it seems fairly obvious, 
but one never knows.  

  i have a RH 8.0 system with the salient directories

  /usr/share/sgml/docbook/
			  xsl-stylesheets->xsl-stylesheets-1.50.0-3

  is it just a case of untarring the new stylesheets into the
same directory (with name docbook-xsl-1.60.1), and resetting
the generic link?

  just trying not to make a mess of things right off the bat.
i'll have plenty of time for that later.

p.s.  i went looking for an RPM of the new stuff, but found
a "docbook-xsl-129-1" at www.rpmfind.net.  not sure what that's
all about, but i'm pretty sure i don't want it.
