AMP HTML format specification requires schema:headline instead of schema:name

[dbs]

The AMP HTML format specification at https://github.com/ampproject/amphtml/blob/master/spec/amp-html-format.md states:

The following properties of CreativeWork must be present:
* headline

Please use http://schema.org/name as the required property instead of http://schema.org/headline. schema:name better matches the broad categories of all CreativeWorks, versus the much more article-oriented schema:headline.

Similarly, alternativeHeadline is recommended. It would be better to recommend the broader http://schema.org/alternateName.

When AMP is being used for news articles, I think 'headline', 'alternativeHeadline' are fine. But I agree that for broader applicability the more generic properties would be more appropriate.

+1 to making "name" rather than "headline" a required property. As the Dans have noted, "headline" is not appropriate for some content, but "name" is universally applicable to any CreativeWork.

For example it is not uncommon to see web pages (i.e. CreativeWork sub-type WebPage) without anything like an on-page "headline" at all, but any well-formed WebPage has a <title> tag, where that value for <title> is almost always appropriate for the "name" property.
