OT : CCDP Requirement

Friends,

Can someone please specify what is the exact requiment for achieving CCDP
certification. Cisco websites says"ccna *and* ccda *or *any ccie cert" ...
So if ive done CCNA, CCNP do I only have to write the ARCH exam to get
CCDP or will I first have to give CCDA as well?. Also I believe CCIE written
doesnt count as a certification therefore it is not applicable as well. Also
I believe valid BSCI & BCMSN (retired) are still applicable for the CCDP
requirement.

I would be thankful if someone can clarify.
