https://www.w3.org/Bugs/Public/show_bug.cgi?id=29498 --- Comment #2 from Michael Kay <mike@saxonica.com> --- To add to this: the RFC definition of MUST is: MUST This word, or the terms "REQUIRED" or "SHALL", mean that the definition is an absolute requirement of the specification. Whereas the F+O definition is much more nuanced: When the sentence relates to the arguments to a function (for example "The value of $arg must be a valid regular expression") then the implementation is not conformant unless it enforces the condition by raising a dynamic error whenever the condition is not satisfied. -- You are receiving this mail because: You are the QA Contact for the bug.Received on Friday, 26 February 2016 10:38:25 UTC
