Attach DB problem

I'm running SQL2000 on my development machine. 2 of our clients use SQL2005.
I've read that it's not possible to attach DB detached from SQL2005 to
SQL2000. But by some reason I can do it with the database of one of the
client. When I try to do the same with the second client database I get an
Error 602.
What is correct - database from SQL2005 cannot be attached to SQL2000, or it
can be attached?
Why I can do it with one DB, but cannot with another one. Both DBs do not
give me any problem if I'm attaching them to SQL2005 running on my second
development machine.
Thank you
vovanMy guess is that the one that works was never attached to a SQL2005 instance
to begin with. Even if by chance it seemed to attach I would not trust it.
The system objects are no longer compatible with 2000 after it has been
attached or restored to a 2005 instance. Bottom line is that it is NOT
backward compatible.

I was mislead by the fact that the client uses SQL 2005 Management Studio to
manage their SQL Server. But the version of SQL is 2000.
