Do you mean a spec from Visa?
It is
"3-D Secure: Protocol Specification
Core Functions v1.0.2
July 16, 2002"

Unfortunately, I can't give you an URL where to download this
document. It is not distributed freely.

But I think, I can repost here a part of 3D-secure DTD:

<!ELEMENT ThreeDSecure (Message)*>
<!ELEMENT Message ((CRReq | CRRes | VEReq | VERes | PAReq |(PARes, Signature) | Error))>
<!ELEMENT PARes (version, Merchant, Purchase, pan, TX, IReq?, Extension*)>

Examples of ThreeDSecure messages was already published in this forum.
For example, see message:
