Release 2022-06-01 pre-release 4


This bundle holds optional files that are loaded in certain situations by kernel code (if available). For example, the new (as of 2021/12) \DocumentMetadata command in the kernel loads a file from here holding the real payload. While this code is still in development and the use is experimental and mainly for the tagging project, the code is stored outside the format so that there can be intermediate releases not affecting the production use of .

Once the code is finalized and properly tested it will eventually move to the kernel and the corresponding file in this bundle will vanish. Note that none of these files are directly user accessible in documents (i.e., they aren't packages) so the process is transparent to documents already using the new functionality.

Current support code in the bundle

Support for \DocumentMetadata

New output routine code (under development)

  • so far there is a first implementation of footnote support
