PSVI support

/ Innovimax SARL <innovimax@gmail.com> was heard to say:
| By the way this implementation dependent thing is reported twice in A.1
| [[
| 23. Whether or not the pipeline processor supports passing PSVI
| annotations between steps is implementation-defined. See Section
| 7.2.3, "p:validate-with-xml-schema".
| ]]
| and
| [[
| 28. It is implementation-defined whether additional information items
| and properties, particularly those made available in the PSVI, are
| preserved between steps. See Section A.3, "Infoset Conformance".
| ]]
|
| Any thoughts ?

I think the duplication is probably ok. I don't really want to remove the
note from either location.
