The phonebcp and framework documents are unusual in that they make very broad claims to cover all emergency calls over IP.  Since there are other mechanisms that are likely to be used in some environments,  it's important to clarify that while these documents describe a solution they do not describe these other environments nor interoperbility with solutions used in those environments.

Per the definition of an applicability statement, all of phonebcp can be considered to be one.
