Yes.

As long as you do not require the list-item markers to be aligned with
anything, the above can be specified with:

  P { text-indent: 2em }   /* or whatever */
  OL { list-style: lower-roman }
  LI { margin-left: 2em }

You're right. The ascii rendering is misleading as it stands (.. but
let me run it through Bert before adding it to the forthcoming errata
sheet). With the keyword value 'outside', the marker will be put
outside the box and the box will be formatted and positioned as any
other box.

With a keyword value of 'inside', the box will be posisioned used the
familiar margin/border/padding onion, and the marker will be put in
front of the content within the box.

If their display type is set to 'inline' they are no longer
block-level elements. For list items, this means that there will be no
list-item marker attached to the element.

E.g.:

  LI { display: inline }

  <UL>
  <LI>foo 
  <LI>bar 
  </UL>

may be rendered as:

  foo bar

The space between "foo" and "bar" is achieved by having spaces in the
HTML source (but the SGML rules on how to collapse white space around
tags may complicate matters). Alternatively, one could add some margin
and/or padding around the elements through the style sheet.

Sorry for entering the discussion so late.
