Default Element Form
|
An element or attribute's form is either
qualified or
unqualified. A form of
qualified means that each time an element or attribute is referenced in the schema document, you must specify the prefix of its namespace. Every element and attribute has a
form attribute. If it is not explicitly defined, the schema processor checks the default attribute form specified for the
Schema node. For example:
If the form for the element
topElem (or, the default form for elements) was defined to be unqualified, the reference could have used
ref="topElem".

Default Attribute Form

Default Blocked Definitions
|
If an element does not have its own blocked or final definition, the schema processor uses the default blocked or final definition you specify here.
