nigelmegitt has just created a new issue for https://github.com/w3c/ttml2:

== contentProfiles and processorProfiles delimiters possibly ambiguous ==
The delimiter used to separate profile designators in `ttp:contentProfiles` and `ttp:processorProfiles` is `<lwsp>` which includes space characters, however according to the reference https://www.w3.org/TR/xmlschema-2/#anyURI the `xsd:anyURI` type can contain non-percent-encoded spaces in their lexical representation, albeit they are discouraged.

Therefore the delimiter as defined at present may result in false separation of URIs where it is not intended.

I would resolve this either by changing the delimiter, or preferably, by requiring percent encoding of the URIs which results in them no longer containing space characters.
