TSAS — Section 4.1 Initial Contact and Authentication

While largely similar to the Parlay Trust & Security Management functions, there are a number of significant differences. In particular there are TSAS-defined methods that are not supported by Parlay 2.1, and vice versa. Also, where methods are common or at least similar in functionality, there are subtle differences in the parameter definitions. I have highlighted many of these as follows:

Section 4.1 Initial Contact and Authentication

· 4.1.1 Initial Interface, initiate_authentication: DomainId data type is a string in TSAS and a tagged union in Parlay
· 4.1.2 Authentication interface, select_auth_method: AuthCapabilityList is a "list of strings" in TSAS and a "string of (comma delineated) sub-strings" in Parlay

The issue is not longer relevant, no alignment with Parlay
