@pgundlach,

this line

https://github.com/speedata/publisher/blob/750feb974ddb169f469d814fdf4975a7e99b7ac4/src/lua/publisher.lua#L7172

is responsible for code such as:

<<
  /Params <<
    /ModDate (D:20220824132726+00'00')
  >>
  /Subtype /text#2Fxml
  /Type /EmbeddedFile
  /Length 5398
>>

But without /Size in /Params, Acrobat won't display file size.

nosize-fs8

So the final code should read:

<<
  /Params <<
    /ModDate (D:20220824132726+00'00')
    /Size 5398
  >>
  /Subtype /text#2Fxml
  /Type /EmbeddedFile
  /Length 5398
>>

This would make a similar image (taken from another PDF document):

size-fs8

I'm afraid I cannot provide a patch, since I don't know how /Length is included from the Lua code.

Many thanks for your help.

Many thanks for the implementation.
