Discard.  PIs in the DTD (that is, in the external subset or
in external parameter entities) belong to the document,
not the schema.  They shouldn't be read by the XSchema processor
as part of the schema.

Interpret and regenerate.  There is no requirement that the output
of a converter have the same text encoding as the input.

It should be said generally that comment declarations may be
freely generated by converters in either direction ad libitum.
They may copy them, discard them, or invent them.  (In particular,
a converter may copy over the whole of its input as a comment,
or as many comments, for documentation's sake.)
