[ttml2] Define fixed values for xlink:{actuate,type}. (#1039)

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

== Define fixed values for xlink:{actuate,type}. ==
Even though TTML2 does not specify the use of `xlink:actuate` or `xlink:type`, their semantics (as defined by [XLink]) still apply, and, in particular, their values (and consequent semantics) are presently defined in the TTML2 schemas as `#fixed`, with values:

```
xlink:actuate = "onRequest"
xlink:type    = "simple"
```
