Identifier for node_metatypes.
node_metatype identifiers take the following form:
absolute-uri ['#' proto-id ['#' proto-id [...]]]
A node_metatype identifier is basically like an absolute URI; except the fragment identifier syntax has been extended to support referring to nested PROTOs.
For example, supposing the following VRML world resides at http://example.com/example.wrl:
#VRML V2.0 utf8
PROTO Outer [] {
PROTO Inner [] { Group {} }
Group {}
}
The node_metatype_id string for Outer would be http://example.com/example.wrl#Outer; and for Inner, http://example.com/example.wrl#Outer#Inner.

Construct from a std::string.
| [in] | id | the identifier. |
| std::invalid_argument | if id is not a valid node_metatype identifier. |
| std::bad_alloc | if memory allocation fails. |
