About PDF / X, PDF / VT, PDF / E, PDF / UA

Hello okabe.yasufumi,

Since these document types are subsets of PDF, they should work with redaction and annotations. However, we cannot guarantee that these formats will validate in their respective formats afterwards.

PDF/UA especially will no longer validate since it requires the data to be kept in the document after redaction, but for others you can try it out.
