How to support custom prompt format?

[ti3x]

Say for example I want to serialize a poml representation before sending a prompt to a DeepSeek model that has very particular rules on prompt template, how should I do that in the context of POML

Render the POML to a pure text format like markdown or XML before sending to deepseek model. POML is never meant to be sent to the model directly.
