We understand that you are working hard to tackle the huge list of features which are required to accurately render MSWord documents of all shapes and sizes and that such an ambitious undertaking will take time to complete. Until the vast majority of features are supported however, we will continue to see some of our users alert us that their documents did not render as expected.
As a stop-gap measure I want to throw out an idea to have your API support a validation check which would report any unsupported items found in a document, and their location (if applicable). If we could see ahead of time that a document will not render accurately due to containing drop caps, “tight” or “through” wrapping styles, etc then we could proactively message our users about what alterations they could make to their document. This seems like it could be a useful feature for everyone. We would be able to shorten the feedback loop to our users about why their documents did not render as expected and you could see less redundant support tickets for currently unsupported features.
