Comment 15 for bug 1189989

Galen pointed out to me in IRC (http://irc.evergreen-ils.org/evergreen/2017-05-24#i_306319) that I was looking at the wrong base.tt2 file when I made the remarks about XHTML 1.0 and not being able to use the HTML5 date element in the OPAC in comment #14. It turns out that we do, indeed, use HTML5 in the OPAC, so I'm going to alter the plans a bit and try this with a date input type.

Firefox does not, yet, have full support for this widget but recent versions do appear to work rather well with it. At least, Firefox 53 recently showed a format hint inside the text box that a date was expected in the locale format. (Yes, I meant locale for the locale of the browser.)
