Declare a namespace.
A NamespaceDecl is part of a prolog and declares a namespace
for later use in the query body or module. It consists of the keywords
declare namespace, an NCName that represents the
namespace prefix, and a string literal, which is the namespace URI.
There is a number of namespace URIs predeclared that you can use without a namespace declaration of your own. These are:
| Prefix | Namespace URI |
|---|---|
fn |

local |
http://www.w3.org/2004/07/xquery-local-functions |
tdf |

tf |
http://namespaces.softwareag.com/tamino/TaminoFunction |
xdt |

xf |

xml |
http://www.w3.org/XML/1998/namespace |
xs |
http://www.w3.org/2001/XMLSchema |
Note:
You can also declare a namespace directly in an element constructor,
e.g.: <library
xmlns:dotcom="http://company.dot.com/namespaces/corporate"/>
Declare namespace http://www.w3.org/2001/XMLSchema to use
for constructor functions:
declare namespace xs = "http://www.w3.org/2001/XMLSchema"
Declare company-internal namespace:
declare namespace dotcom="http://company.dot.com/namespaces/corporate"
