Property Documentation

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`
GUID	`g=08081e75-8e5e-319b-954f-f3a7613dc29b`
Opaque (base64)	`b=UXQgZnR3IQ==`

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.
