The buffer is in a (major) mode. You typically
define font-lock patterns for a given mode.
You can define your own major mode using
`define-derived-mode'.
I probably should have mentioned this: To highlight
parts of a string is one thing - use `propertize'
with property `face', for example.
To highlight parts of a buffer is something else.
You typically use font lock for this. Font lock
periodically updates the highlighting, even as
you change buffer contents. It applies a set of
highlighting rules (regexp patterns, for example),
in sequence.
