| Attribute Value Type | |
| Text from specification | |
|
The attribute must have been declared; the value must be of the type declared for it. |
|
| Explanation | |
|
All attributes used on elements in valid XML documents must have been declared in the DTD, including the xml:space and xml:lang attributes. If you declare an attribute for an element, make sure that every instance of that attribute has a value conforming to the type specified. (For attribute types, see the Attribute List Declaration entry earlier in this chapter.) |
