It is not this task that makes it difficult but the context that has to be provided. A profile is a collection of features and extension. An how you structure this features have some semantic meaning. I think that the use of this mechanism is not consistent through the (current) TTML profiles. If you say that you can have a profile document that says "here is my label and what is required to conform is written in the corresponding specs" that this may work. But I assume that you have to list features and extension (?). -- ------------------------------------------------ Andreas Tai Production Systems Television IRT - Institut fuer Rundfunktechnik GmbH R&D Institute of ARD, ZDF, DRadio, ORF and SRG/SSR Floriansmuehlstrasse 60, D-80939 Munich, Germany Phone: +49 89 32399-389 | Fax: +49 89 32399-200 http: www.irt.de | Email: tai@irt.de ------------------------------------------------ registration court& managing director: Munich Commercial, RegNo. B 5191 Dr. Klaus Illgner-Fehns ------------------------------------------------
