Is <short-name> a mandatory subelement of <taglib> in a TLD?

Question

I was under the impression that <short-name> is a mandatory subelement of <taglib> in a TLD:

<taglib>
    <tlib-version>1.0</tlib-version>
    <short-name>mandatory?</short-name>
</taglib>

Is this correct? I'm getting some mixed answers through web searches (and a few other sources).

Answer 1

http://docs.oracle.com/javaee/1.4/tutorial/doc/JSPTags6.html lists it as optional. I would tend to consider that as authoritative. However, the ultimate answer is that it will depend on the implementation in your web app server. Which one are you using?
