To help catch authoring errors like the one in bug 14595, we could improve the
validity constraints related to itemprop a bit. Specifically, if itemprop
appears of any of the following attributes, require that the attribute is

meta: content
audio, embed, iframe, img, source, track, or video: src
a, area, or link: href
object: data
data: value

(Matching how itemValue works.)

If one deliberately wants an empty value, one can simply use e.g. <data
itemprop="prop" value=""> instead of <data itemprop="prop">.
