196 The rules given in this variable are invoked first, followed by

199 Each member of the list is either a function, or a list of the form:
201 (REGEXP/SYMBOL TEXT-BEGIN-GROUP REPLACEMENT-TEXT/FUNCTION/SYMBOL)
203 REGEXP is a regular expression, or symbol whose value is a regular
204 expression, which is searched for using `re-search-forward'.
205 TEXT-BEGIN-GROUP is the matching group within that regexp which
206 denotes the beginning of the actual text to be marked up.
207 REPLACEMENT-TEXT is a string that will be passed to `replace-match'.
208 If it is not a string, but a function, it will be called to determine
209 what the replacement text should be (it must return a string). If it
210 is a symbol, the value of that symbol should be a string.
212 The replacements are done in order, one rule at a time. Writing
213 the regular expressions can be a tricky business. Note that case
214 is never ignored. `case-fold-search' is always bound to nil
215 while processing the markup rules."

285 a closing tag and/or an optional set of attributes, whether it is

287 within the delimited region.
289 The tags themselves are deleted during publishing, before the

291 the beginning and end of the region surrounded by the tags. If
292 properties are allowed, they are passed as a third argument in
293 the form of an alist. The `end' argument to the function is

297 the function is called. Wherever point is when the function finishes
