[osis-core] osisCore.1.9.9 attached!

[Todd Tillinghast]

Patrick,

In OSIS.1.9.9 xml:space has disappeared everywhere but on <osisText>
where its values is defaulted to "default".  <osisText> is correct but
we need the attribute available on all other elements (with the
exception of pure milestones, but there is not harm of putting it there)
as optional with no default.

IE: Add <xs:attribute ref="xml:space" use="optional"/> to global*Type
and other places where global*Type are not present.

I think this is simply an oversight.
