"""
DocInfo

Although it was possible to read tag directives before this, all handle/prefix
pairs for all documents in all streams were stored in one dictionary per
YAML instance, making it impossible to distinguish where such a pair came
from without sublassing the scanner.

ToDo:
DocInfo can be used by a yaml dumper to dump a class
- if connected to the root of a data structure
- if provided to the dumper?
