I don't think implementing things "for kicks" is a useful use case. In 
general adding spec features to allow other specs to build on top of 
that is a bad idea IMHO, I basically never use other public APIs when 
implementing features, instead I use internal APIs that are better fit 
for my needs.

In any case, using element traversal you can decently easy check if 
content is skipped so that you can indicate an error, simply check if 
myElem.nextElementSibling != myElem.nextSibling
