Narrative:
During IMC CAT 3 approachs to dfw; approach and tower was assigning 180 KTS to the FAF for runway 17R. The aircraft ahead of us executed a missed approach. We declined ATC's request to fly 180 KTS to (what amounted to 5 mi from the end of the runway). Approach said if we couldn't comply then they would have to break us off from the approach. I (captain) said to do whatever you have to do; I would not accept that. They broke us off. Prior to next approach; I stated; again; that I would not accept 180 KTS to the marker; and to go ahead and let me know now so I could go ahead and begin executing my alternate airport plans. Approach complied with my request and we flew a normal CAT 3 autoland to runway 17C; this time. These requests from approach and tower are not within the operational parameters of our aircraft; procedures; and training.
