Short answer
In Calenco, each content block can become a reusable module: warning, procedure, specification, table, image, or even a very small fragment. Writers assemble these modules instead of copying text between documents.
If a specification changes, the source module is edited once. Documents that reuse that module can then be regenerated with up-to-date information, whatever their language or publication output.
This model is critical for product ranges, software versions, multilingual manuals, and regulated documentation. It reduces errors, speeds up updates, and gives the entire corpus a reliable structure.
