Hi Martin, all,

In the recent [1] "Periodicals, Articles and Multi-volume Works" proposal
[2] from the SchemaBibEx group, we've suggested a widening of isPartOf,
along with the addition of a hasPart property, to cover general
composition. (This is actually an inclusion of an earlier proposal from us
[3].)

Since the proposal is to use CreativeWork (of which both WebPage and
WebPageElement are subclasses) for both domain and range of these
properties, this case would be solved as well.

Cheers,
Niklas
