Unknown properties with rendition: prefix are invalid #1327
Description
One of the changes in w3c/epub-specs#2134 is to disallow authors from adding custom properties with the rendition: prefix.
In practice, this means only the following are valid in the package metadata:
- rendition:layout
- rendition:orientation
- rendition:spread
- rendition:viewport (but deprecated)
- rendition:flow
- rendition:align-x-center
And only the following are allowed as spine overrides:
- rendition:layout-pre-paginated
- rendition:layout-reflowable
- rendition:orientation-auto
- rendition:orientation-landscape
- rendition:orientation-portrait
- rendition:spread-auto
- rendition:spread-both
- rendition:spread-landscape
- rendition:spread-none
- rendition:spread-portrait (Deprecated)
- rendition:page-spread-center
- rendition:page-spread-left
- rendition:page-spread-right
- rendition:flow-paginated
- rendition:flow-scrolled-continuous
- rendition:flow-scrolled-doc
- rendition:flow-auto
