Note this is a constraint on the attribute declaration component.

you mean '... not _global_.'
This is stated clearly in 4.3.1 under max and min occurs -- where is
the unclarity?

Again, max/minOccurs are _not_ attributes of the <attribute>
declaration -- various values of these properties of the attribute
declaration component correspond to various values of the 'use'
attribute, per 4.3.1.

Will be fixed, thanks.
