# Deviations from UD

Version 2.7 of the English UD treebank conforms to the UD guidelines in
Version 2.13 of the English UD treebank conforms to the UD guidelines in
almost all respects, but there remain the following deviations:

- The UD dependency `flat` is largely only used for person names.
- Dates are not annotated consistently.
- The attachment of punctuation tokens is sometimes not according to the
guidelines.
