Bob, Please confirm that this is working document that you want to hand over to assist a parser developer, and that this document will not be specifically added to the AMI specification. In any case, there is one confusing item. If Model_Specific and Reserved_Parameters are replaced by white space, there would still be two branches with branch names blank. What I have proposed in the new AMI BIRD is that these branches will simply not exist, but for compatibility sake, if they do exists then the branches off these two branches would be treated as if they are off the root branch.

After attempting a spread sheet, and then a formal syntax approach, I opted for a psuedo formal definition in a quick reference style format to show all of the allowable choices. I did not add some special cases and exceptions since my top priority is to understand just the basic rules. The first cut is a blend of the existing V5.0 syntax and the proposed syntax with some changes to assist graceful migration of the Reserved_parameters. I have included parameters that might be dropped and some others that were originally proposed but withdrawn in the new BIRD just to keep them visible. A few technical questions and concerns will arise from this, and there are probably several mistakes. The Model_specific portion still needs more development since the (tree) structure might support a very general hierarchical structure. So I expect to revise this file as we decide and clarify what we want.
