Boomi Tip: Importing DTD into XML Profile
Boomi allows us to create a new XML profile by importing from a XML Schema. However, it can only support the common XML schema, XSD. So, what to do if you only have DTD schema? One quick solution is to convert the DTD to XSD by using the free conversion tool that is provided by W3C.
Once you have generated the XSD, you will just need to import it into Boomi.
