I think you've misunderstood what I meant; If you have a string, how do you
append to it? First you need to count the length of the string, before you
can copy onto the end (etc). Verbosity is just a scaling factor. Having to
do a larger number of string operations decreases performance.

Glad you agree ;)
Again, discussing the abstract can be dangerous, as it's harder to
understand what you're trying to achieve and your motives for it -- my first
reaction way back in the thread was "why author in XHTML? Why not start with
an intermediate and convert for all outputs?" You've since hinted at why
(I.e. You have a specific editor you'd like to support, and you have to
output to legacy systems)

SAC is just a library (or API) as I understand it, so it's on a par with all
the XML parsers out there; so SAC is not an application purely for
generating XML, but instead a library for interpreting CSS -- which
undermines your argument; SAC being created for interpreting CSS, not for
porting it to XML.

By the way, is XSL-FO a close enough port of CSS to XMLisms for you?
