True, but being pedantically correct would obscure the sentence
completely, I fear. You'd need some sort of arm-waving about
"the slot numbers and values entries corresponding to statistic kinds
STATISTIC_KIND_MCV and STATISTIC_KIND_HISTOGRAM", or something like
that :-(. That might be appropriate in catalogs.sgml but I think it
will just confuse the readers of perform.sgml.
