What does preferred mean? Can I take the non-preferred interpretation? Also, since the longest token rule suffices for many grammar implementations, we would like the specification to make the impact of delimiting terminals non- normative. If I have the expression 0+a-b, a parser can know that a-b is taken as the longest token, and that the expression (0+a)-b will be tokens 0 + a - b. 3164 1 scott_boag 2005-05-17 18:19:42 +0000 #1 in the webster's definition. :-) 1 : to promote or advance to a rank or position It works for me, but I think we could substitute the term "used". XPath 1.0 says "the longest possible token is always returned." 2742 2 chamberl 2005-06-11 03:40:30 +0000 On 5/19/05 the working group approved Scott's proposal to change "preferred" to "used". Scott, will you please make this change? 4464 3 scott_boag 2005-07-09 10:28:56 +0000 Done. 14176 4 jim.melton 2007-02-25 23:54:40 +0000 Closing bug because commenter has not objected to the resolution posted and more than two weeks have passed.
