You're not mistaken, it's quite far from PCREs. Generally you'll be using
posix expressions instead of the \char notation; so \d becomes [[:digits:]],
\w becomes [[:alpha:]], etc. Substrings are also quite different in the
handling (read: not nearly so nice). If you're on a dedicated server there
is a CFX tag for PCREs in CF that makes life so much easier for string
parsing and data validation.

Here's a link from the old CF4 manual:

lar_Expressions/adv04.htm
Also read the reFind(), and reReplace() reference carefully (not the
clearest of tech writing I know):

(only time I've ever seen back refferencing used properly in a tutorial on
CF regexps)
http://www.figleaf.com/figleafhome/cfug/CFUGDec99/regexp/
Print refferences:
Ben Forta's "Advanced Web Application Development" by Que
List of posix character classes:
alnum - alpha-numeric characters
alpha - alphabetic characters
blank - tab and space
cntrl - control characters
digit - decimal digits
graph - all printable characters except space
lower - lower case letters
print - "printable" characters
punct - punctuation
space - whitespace characters
upper - upper case letters
xdigit- hexidecimal digits
All the standard control characters work w/in the mask, so ^ $ ? *
{num,num} etc. Sub expressions (if you set return sub expressions to true)
are returned as start postion and length in an array, and the mid() function
has to be used to retrieve them. So for basic validation CF is okay, but
complex string handling gets long and tricky compared to Perl (but nothing
so annoying as string handling in C was).
If you don't get the more advanced stuff (ie. back referencing, substring
manipulation, etc.) from the docs, I can send over some production code
examples that might help.

I also believe that I should use Regex, but I can't find any decent
reference for it for CF. It seems to be quite different from Perl's regex.
Am I mistaken?

Not sure if you've ever used regexps, but that is what you want. Check out
reFind() and the other regexp functions.

Is there a way to validate against a mask like lets say in MS Access. Is
there a CF function that does this?
Something like
ConformsToMask("mm-dd-yyyy","01-17-2001")
or
ConformsToMask("###-###-####","111-111-1111")
