[jsr-314-open] is <f:view contentType="text/html; charset=iso-8859-1"> a valid notation?

Hi I found some examples on mojarra distribution uses the following notation to define content type and encoding: <f:view contentType="text/html; charset=iso-8859-1"> Is that valid? (it has sense) in JSF 2.0 Rev A Change Log it says: C051 Errata TLD Docs for Facelets f:view needs contentType and encoding attributes but checking previous mails on this list, in the topic: [jsr-314-open] Errata: contentType and encoding on f:view it says this two params should be removed from facelet taglibdoc. regards, Leonardo Uribe
