The above assumes the attribute has a constant value. Obviously if one changes the value of an attribute, then one _might_ have a different range of interpretations for each value.
Consider, however, the semantics assigned by XML Schema datatypes. Assuming the following
<foo:bar baz="10" />
<foo:bar baz="010" />
and given the type:
element foo:bar {
attribute baz{xsd:integer}
}
This constrains the range of interpretations given both the element with baz="10" and baz="010" to be the same (I am not constraining the range of interpretations, rather saying that both must have the same range.)
