| 23 | This schema declares XML elements for the 15 DC elements from the
|
|---|
| 24 | http://purl.org/dc/elements/1.1/ namespace.
|
|---|
| 25 |
|
|---|
| 26 | It defines a complexType SimpleLiteral which permits mixed content
|
|---|
| 27 | and makes the xml:lang attribute available. It disallows child elements by
|
|---|
| 28 | use of minOcccurs/maxOccurs.
|
|---|
| 29 |
|
|---|
| 30 | However, this complexType does permit the derivation of other complexTypes
|
|---|
| 31 | which would permit child elements.
|
|---|
| 32 |
|
|---|
| 33 | All elements are declared as substitutable for the abstract element any,
|
|---|
| 34 | which means that the default type for all elements is dc:SimpleLiteral.
