The query functions defined in an XQuery module may also be used for defining a computed index.
For details on computed indexes please refer to Performance Guide > Advanced Indexes.
The XQuery Tool delivered with Tamino provides convenient support for maintaining XQuery
modules.
Serializing Query Results
When Tamino executes a query, it handles the query in terms of its data model: an XML document
is treated as a tree with a document root and different types of nodes. The query result is then
serialized and wrapped into a Tamino response document. You can determine the serialization by
using a Tamino query pragma, or XQuery processing instruction, which always has the form
{?piname?}. Like a regular XML processing instruction, it can have additional information. This
section discusses the available serializations:
■ Suppressing the Response Wrapper
■ Setting the MIME Media Type
■ Defining a Custom Output Handler
Suppressing the Response Wrapper
Normally, when Tamino executes a query, it returns the result using a response wrapper. This is
