Depends on the parser - most do not use the W3C Document Object Model
for their data structure, but e.g. just report events, or build a much
more lightweight tree.

Not usually. The CDATA section (as David Lee said) is just an
alternative to using < and friends; most parsers will turn "
into " in the stream without necessarily reporting anything.
If you want to get CDATA out with XSLT (or XQuery 3) you can do that for
a specific element using serialization options.
CDATA sections are pretty ugly (!) and also tend to be vectors for CDATA
injection attacks, so in most cases they're best avoided.
