As long as the native VLAN is the same on both ends so that the ends of the prospective trunk link can communicate, DTP will be able to form the trunk. The VTP domain is irrelevant. All DTP needs is layer 2 connectivity and the desire (on both ends) to trunk. :-)
In fact, one of the requirements for a VTP domain to exist is that trunking must be enabled between the switches. In light of this, I would say that VTP is dependent on DTP or DISL but DTP and DISL are NOT dependent on VTP.
