Hi, CSS property

footnote-style-position

is marked as a Prince extension with asterisk in the reference guide, but it doesn't seem to have an alias with vendor prefix, as other extensions do.
In other words, this is not working in Prince 14:

-prince-footnote-style-position: inside;

Would it be possible to add an alias, so CSS validators can ignore the non-standard property?

Thanks,
Tom De Herdt
