wrong namespace [was #8320]
The linking file shows a validation error, because the namespace for tei needs to be one including svg, as http://www.tei-c.org/release/xml/tei/custom/schema/relaxng/tei_svg.rng
I am not sure if the ".rng" causes problems in the lab, as it doesn't support rng yet. Maybe this can be cleared with Thorsten.
