I care less about this one than others, though, since there's little risk of this replacing the ordinary use of the word and making the language less expressive (as in the case of "envious" vs "jealous"). "Avoid doing this" remains good advice, but it's not so bad as errors go. I mainly brought it up as an example of incorrect use surpassing correct use.
It's in a similar class to using "X and I" where it should be "X and me". It causes little harm, most of the time, as far as hindering communication, but getting it right is still preferable to getting it wrong, which means that any decent guide will classify it as a mistake, unless (as is always the case) one means to commit the error, for some reason. That's the case despite the incorrect-I error having, I'm sure, a longer and more widespread history than "to be comprised of"—the history doesn't save it from being something to avoid. Maybe some day it will.
[EDIT] Sorry, that was needlessly curt. I don't think we actually disagree that much anyway—I'm not advancing prescriptivism, and this issue doesn't bother me that much (I was just using it as an example!), though I do notice it. I can find support in the dictionary for my use of "incorrect" here— :-) —but it was probably an incorrect word to have used to express what I was getting at in the first place, and my poor choice there may have been the cause of much of this exchange.
Oh well -
Someone upthread implied that the purpose of a descriptivist dictionary is to help readers/hearers to understand unfamiliar words, not to guide writers/speakers in correct usage. Thing is, they're all descriptivist. There are opinionated guides like Fowler (and the subject of this article! /on-topic), but I don't know of an opinionated lexicon.
