xsl:preserve-space

I am having a hard time understanding how to implement this tag.  The spec says
to list the elements that I would like to preserve space for like this:

<xsl:preserve-space elements="..."/>

is the list of elements just space delimited like so:  elements="elem1 elem2
elem3"?  what i would really like is to preserve the white space of the entire
xsl
style sheet as well as the xml elements.  does anyone have any ideas?  thanks.
