pub fn embed_reference(html: &[u8], href: &str) -> Result<Vec<u8>, Error>Expand description
Reference an external Manifest Store, as a link element in the document
head.
Any existing C2PA manifest elements are removed first. Fails with
Error::NoHead if the document has no </head>.
href is written into an attribute verbatim except for &, <, and ",
which are escaped. A URI containing those characters is unusual but a
document that carries one must still parse.
