Chooses one matching parameter from a list of parameters to consider. The list of parameters to consider is just | |||
names. For parameters that may be enumerated, the position of the numerator in the parameter name is identified | |||
by the '#' so |author-last1= and |author1-last= are represented as 'author-last#' and 'author#-last'. | |||
Because enumerated parameter |<param>1= is an alias of |<param>= we must test for both possibilities. | |||
Generates an error if more than one match is present. | |||
