[oXygen-user] epub3 epubcfi support

[Oxygen XML Editor Support (Radu Coravu)]

Hi Peter,

Oxygen uses for validating XHTML documents the schemas developed by the 
EPUBCheck project.

The reported error is this one, right?

> E [Jing] value of attribute "href" is invalid; must be a URI

According to the XHTML 5 specification the @href value of the <a> attribute:

> http://www.w3.org/html/wg/drafts/html/CR/links.html#attr-hyperlink-href

  needs to be an URI which would mean that it should have all 
URI-illegal characters escaped like:

> epubcfi(/6/8%5Bchap05ref%5D!/4%5Bbody01%5D,%20/156%5Bp142%5D/1:0,%20/157%5Bp143%5D/1:0)

but I'm not quite sure of this.

Regards,
Radu
