Use elementFormDefault to Hide\/Expose Namespaces<\/h2><\/span>\n

* ‘elementFormDefault’ is a binary switch attribute in the schema to control if the origin (i.e. namespace) of each element should be
\n– hidden (elementFormDefault=”unqualified”)
\n– or exposed (“elementFormDefault=”qualified”).
\n* elementFormDefault defaults to “unqualified”
\n* All schemas must have a consistent value for ‘elementFormDefault’ in order to hide\/expose all<\/strong> elements.<\/p>\n

Hide Namespaces<\/h3><\/span>\n

* Advantages:
\n– Simplicity
\n– Flexibility to change the schema without impact of instance documents.
\n* Howto:
\n– Set elementFormDefault=”unqualified” in all schemas.
\n– The element must not be globally declared.<\/p>\n

Best Practices<\/h3><\/span>\n

* Make two identical copies of a schema:
\n– One with elementFormDefault=”qualified”
\n– One with elementFormDefault=”unqualified”
\n* Minimize the use of global elements and attributes.<\/p>\n

Notes<\/h2><\/span>\n

* Global elements and attribute must always be qualified.
\n* Use <include> to include schema with same namespace.
\n* Use <import> to include schema with different namespace.<\/p>\n
