Should I use publishDate or datePublished for schema.org Review markup?

Question

I'm using schema.org’s Review and I would like to know if I should use publishDate or datePublished properties.

According to the doc (http://schema.org/Review), it seems to be datePublished but in the example they use publishDate.

Answer 1

I would lean towards 'datePublished', as I can't find 'publishDate' in their full documentation.
