Schematron is a schema language for XML documents that allows for more flexible and expressive validation than traditional XML schema languages like XML Schema and DTD. Schematron uses a rule-based approach to validation, allowing for complex business rules and constraints to be expressed in a clear and concise manner. It is often used in conjunction with other schema languages to provide more comprehensive validation of XML documents.

Schematron can be used with AI to automatically verify documents using an AI model. This can be done by integrating the AI model into the Schematron rules to check for specific criteria. For example, the AI model can check for the use of active/passive voice in the document and the Schematron rules can be set up to flag any instances where the wrong voice is used. Similarly, the AI model can check for adherence to a specific style guide and the Schematron rules can be set up to flag any deviations from that guide. The AI model can also check if the document answers a specific question and the Schematron rules can be set up to flag any instances where the question is not answered. Additionally, the AI model can check for spelling and grammar errors and the Schematron rules can be set up to flag any errors found by the model. Overall, integrating AI with Schematron can help to automate the verification process and ensure that documents meet specific criteria.
