       Done. Made it unexported but still added documentation, including a link to the Java equivalent.

   Don't merge until #14665 is in. I've included that change in this PR just to get it working so it can pass tests, but I plan on removing it from this PR once it's been merged separately.

Review comment:
       Looking at how the PrefixPayload is used, I'd recommend not exporting the type, and avoiding over documenting the self explanatory type. It would still need to be registered, (as you're doing) and have it's Data field exported.
   
   However, since this is part of the Xlang examples, it's reasonable to keep it Exported and document what it is (a type to configure the Prefix transform), how it's used (an internal type to be schema encoded so the xlang transform can use interpret it), where that format comes from (github link to the Java format/equivalent is fine) and that it's exported for example documentation purposes only.
   
   It's odd to me that the PrefixPayload on the receiving side is expecting a schema with a "Data" field, but if that's correct, that's what it is. I'm glad that it didn't need a field name override struct tag at least.

Review comment:
       Consider adding documentation for what the Prefix transform is, and what it's testing/serving as an example of.
   
   We should probably add similar documentation for all the transforms below as well, but that's out of scope for this PR.
