   Can't really help here, though I think you'd need to declare the
color space (RGB) using (color-space ...), then use that in a (color
...) function as the value of the "color" property in your paragraph
(which the paragraph itself wouldn't care about, but the characters in
it would).
   Can someone who knows what they're talking about help here? :)
(I'd kinda like to know, too... :)  Unfortunately, the DSSSL standard
only briefly touches on this stuff, and leaves several important
details out, instead referring us to another standard (SPDL, I think).

   Well, sosofo stands for "Specification Of a Sequence Of Flow
Objects".  Perhaps a better way to say it would be "Description of
some Flow Objects to be created", but "dosfotbec" just doesn't roll
off the tongue the way "sosofo" does. :)
   Basically, just think of a sosofo as a list of flow objects.  The
standard says that DSSSL doesn't actually deal with flow objects, only
specifications for them, but that's more an implementation view.  As
far as the user is concerned, a sosofo is really just a set of flow
objects.

   In this case, you need an "inline" flow object, which is one that
doesn't cause a line break.  A paragraph is a "display" flow object,
which is one that does cause a line break.
   If you're just looking to apply some different characteristics to a
piece of text in the middle of a line (such as a single word in 6pt
font instead of 20pt, like the rest of the line), the sequence flow
object should work well:
	(element p
	    (make paragraph
	      font-size: 20pt
	      (process-children)))
	(element sub
	    (make sequence
	      font-size: 6pt
	      (process-children)))
   Note, by the way, the (process-children) in each rule.  This would
actually get called implicitly if there was nothing else specified for
content, but I personally find it better to include it explicitly, to
avoid confusion.
