Hi Paul,

For me it is a pleasure to help with this document. To hold all the errata that we find, I have created a wiki page at:
http://forge.gridforum.org/sf/wiki/do/viewPage/projects.glue-wg/wiki/GLUE20Errata

We can hold the information here while we discuss it via email before making a proper errata document.

Regards,
David

Correct.

Your assumption is correct; in fact, the term is defined on page 6.

The two terms '*' and '0..*' refer to the same concept: zero or more items.
Using two terms for the same concept is an inconsistency in the document,
which should be fixed.  I guess this should be recorded in some errata
document (wiki page, etc) initially.  I'm not sure how documents are updated
within OGF.

>From a quick scan through the document I found (only) five places where '0..*'
is used, the remainder are '*'.  Also the term '*' is defined whereas '0..*'
isn't.  So to fix the inconsistency we should change the five occurances of
the '0..*' term to '*'.

That said, I'm also in favour of '0..*' because to me it's meaning is clearer
and is more in keeping with the other term: '1..*'.  I'm not sure how others
feel about changing '*' to '0..*'.

Cheers,

Paul.
