The first error I get on this is that you've constrained "Type" to be
singles or doubles, but the actual value is "Those are football matches".
The next error appears to be because the values you are using for keys have
variable numbers of leading and trailing spaces. If you want these
normalized, don't use the type xs:string.
The next two errors are because your key definitions and references don't
match: your Member elements are matching the content of the Name element,
not the @id attribute, and the Team elements are matching on the @Name
attribute, not the @id attribute.
It always helps, incidentally, to say which product you are using. Then you
might get someone looking at it who is familiar with the error messages
produced by that product.
