Revisiting tag policy: xkeyval tag?

Question

Over on main we had a question: " pstricks and beamer compilation with xelatex results in xkeyval error " and the questioner requested the xkeyval be created and placed on his question.

Following the philosophy outlined in Our set of tags I went ahead and did that. It says packages and classes should get their own tags. xkeyval is a pretty big package and despite the fact that we have had no questions about it yet I think it's merited.

What say you, metafolk? Is the linked meta post still policy?

As it turned out the question was unrelated to the use of xkeyval; that was just the package that threw the error (it was a symptom, not a cause). So I detagged the question and xkeyval is currently an orphan.

Answer 1

Tags for packages are fine. Besides the package tag, I suggest adding the respective concept tag, also if you note such an existing question.

If, for example, you would see a question with only

• the tocloft tag, add table-of-contents

• the natbib tag, add bibliographies

• xr, cleveref or varioref tag, add the cross-referencing tag.

And, of course, if you write a question, choose your tags wisely: specify

• a concept tag: what are you doing, whats desired

• a package tag: what are you using, which is the specific context

• a class tag: but only if you know your question deals with features or options of this class

Answer 2

Although our tagging practice is not consistent in this regard, I think that "tags for packages and classes" is still -- and should be -- our policy in force. Tags like tocloft may not be that important for prospective respondents (who will typically browse questions tagged table-of-contents), but they are servicable for questioners who look for specific advice on, say, \cftXfont.

If a questioner uses a particular tag which later turns out to be irrelevant for his/her problem, it is perfectly fine to remove the tag. If this turns the tag into an orphan (for now), then so be it. Tags for very small or specialized packages may be dispensable, but I reckon too that xkeyval deserves its own tag.

Answer 3

One reason for tagging with packages is that it would be useful for the package maintainers. I wrote in Message to package maintainers that I think that this place would be great for package maintainers to find out about how their package is used and so forth. So to make the place as easy for package maintainers as possible, tagging questions accordingly makes sense.

And note that this is beneficial to the questioner as well, since who better to answer a question on a particular package than the person who wrote it?
