identifier : string |
Identifier of the node. The identifier has to be given in one of the following types.
| Type | Example |
|---|---|
| Numeric | i=23 |
| String | s=MyStringIdentifier |

It is possible but not recommended to include the namespace index ns=X;s=.... In this case the given namespace index is internally stripped off the identifier and set to the namespace property.
ns : string |
Namespace of the node identifier. The identifier can be the index as a number or the name as string. A string which can be converted to an integer is considered a namespace index.
