In the FIX SBE Standard 1.0 it is suggested to use imports for common encodings. (see: https://github.com/FIXTradingCommunity/fix-simple-binary-encoding/blob/master/v1-0-STANDARD/doc/04MessageSchema.md#importing-encodings)

Issue #556 was closed with the reason that it is not possible to use both imports and schema validation with a link to a StackOverflow question. In that same SO question it is also stated that the imports should be handled before validation, so it should be possible.

Can I ask why it is not possible for the SBE-tool to support this? I would rather have the tool that does the processing do all of the processing, instead of requiring yet another tool to do the pre-processing.
