I have a map that uses a custom XSLT. When running the "Test Map" within VS I get the expected outcome, even on my "fail" instance that does not comply with my destination schema. But when deployed to my BizTalk Server the "fail" instance does not fail.
So the question is, when using a custom XSLT is the instance not validated against the source and destination schemas provided in the XSLT?
If not, what is applied on a map when using the visual mapper since this seems to work?
