Detailed Description

Tag represents a mark that can be added to a node to mark that the node is of certain kind.

For example transparent nodes can be marked with a "Transparent" tag. The transparent nodes can then be rendered in a different way than other objects by using a tag filter that selects only nodes with the "Transparent" tag.
