## Description
 **SVG\_ADD\_NAME\_SPACE** ( svg\_ref ; prefix {; URI })

Adds xmlns attribute to the root of the DOM tree (xmlns:prefix="URI")

If **svg\_ref** is not the reference of an element "svg" the attribute is added to the root of the tree.

Prefix could be a constant :

* svgNS for the standard SVG namespace. 
* xlinkNS for the standard XLink namespace.

<br/>If prefix is not a constant, URI is mandatory otherwise an error is generated
