okay, i'm showing that i'm an xml newbie but i'm confused.

what's the difference between declaring an element having
CDATA content and using a CDATA section?

can i declare that my element will contain a CDATA section
in a schema? if so, how?

also, not quite related, is it valid for a CDATA section,
not the same one, to contain binary data? if so, are there
restrictions the binary data must conform to (no null values
for instance)?
