Schematron has become a very popular language in the XML world. In the last few years, Schematron started to be used more and more and in numerous domains. One of the reasons Schematron started to become more popular is because you now also have the ability to define actions that will allow the user to correct the problem, rather than just presenting an error message. SQF has made Schematron more powerful and became a powerful language in itself.
SQF has also evolved by adding the multilingual support or the support to generate quick fixes dynamically. The specification has became more accurate and the implementations more stable. Developers are discovering new ideas for working with Schematron quick fixes even outside of Schematron language.
