xau'o'o
experimental cmavo mekso convention cancellation This word is followed by an evaluated li clause (yielding specifically a number n, which probably is a nonnegative integer, or a set thereof (the elements of which will also be denoted by simply n, for simplicity) ). It repeals the nth most recent/last convention (counting backward) for mekso/mathematical expressions defined by xau'e'o. In order to repeal all such conventions (returning to the conventions specified by some grammar collection), the set should include all integers less than or equal to some sufficiently large integer (which might be ro); ro denotes the first rule defined (the last rule counting backward from the most recent) it does not reference "all rules defined"; the most recent rule is denoted by pa. Any named body/ordered collection of rules (such as ".pemas.") is treated as being only one rule for the purposes of such counting.


xau'e'o
experimental cmavo mekso convention default specification/definition (explicit) This word is followed by a list of rules. The rules specify the convention by which mekso or mathematical expressions (of various kinds) are to be interpreted. Such conventions are taken to remain in effect until the end of the discourse, until repealed, or if the come to conflict with subsequent rules so marked; in the lattermost case, the subsequent rule takes precedent and the earlier rules that are in conflict with it are ignored only in the most minimal domain of application possible (for example, a rule saying "left composition of functions is denoted by "°" in all cases" could be followed by a rule saying "when a linear transformation can be represented by a matrix, left composition of two such functions is equivalent to left multiplication of their corresponding matrices and so their left composition may be represented simply by juxtaposition as is typical with/for multiplication" with result being that "°" is to be used for all left compositions of functions except when both functions being composed are linear transformations admitting matrix representations, in which case "°" could be used but adjacency alone is sufficient to denote their left composition). Collections of rules (ordered in increasing precedence) can be named and referenced by such name expressed instead of those rules at length (such as calling a (specific) rather simple set of rules defining the order of operations ".pemas."). See also: xau'o'o.
