How I configure Apache Virtual to support all sub-domains

I have some differences domains and sub domains
like this
abc.com
xyz.com
xxx.com

and sub domain
ftp.abc.com
www.abc.com
xxx.abc.com
...

all domains/sub-domain point to 1 IP address
I use mydomains.com as name server that can support "ANY ALL SUBDOMAIN" to 1 IP
For example
I can ping  a.bc.d.e.f.asdfa.sadfs.sdaf.fdsaf.ds.abc.com == my ip
but I not have to configure that subdomain

Now i can configure VirtualHost for all domain that I have, but
can not set for any all subdomain

QUESTION
1. Can apache support any all subdomain virtualhost?
2. If it can, how to configure that. if not why? where is document to refer

I am not sure it works (not tested). I think each ServerAlias must be defined using regular expressions:

ServerName xxx.abc.com

ServerName abc.com
ServerAlias !(xxx).abc.com

(all is not tested)
