Hello,

I was firming up my XML schema knowledge through the referenced web page
and spotted what I think is an inconsistency.  Forgive me if I misinterpret
things but the following paragraph seems to be at odds with the table entry
below it.


The schema processor treats defaulted elements slightly differently. When
an element is
declared with a default value, the value of the element is whatever value
appears as the
element's content in the instance document; if the element appears without
any content,
the schema processor provides the element with a value equal to that of the
default
attribute. However, if the element does not appear in the instance
document, the schema
processor does not provide the element at all. In summary, the differences
between
element and attribute defaults can be stated as: Default attribute values
apply when
attributes are missing, and default element values apply when elements are
empty.


versus table at -- http://www.w3.org/TR/xmlschema-0/#cardinalityTable

(0, 1) -, 37
                                optional, -, 37
                                             element/attribute may appear
once; if it does not appear
                                             its value is 37, otherwise its
value is that given
