Hi, (apologies if this should have been posted already, I have not seen it yet after trying twice.) We are currently defining a format for medical data storage (hrmconsensus.org). The full version is available <a href="http://hrmconsensus.org/media/hrm/xhrm/xhrm02/xhrm0_2.xsd">here</a>. In the simplified example below, we have the always mandatory deviceTyp. For patientsType, we would like to have a global conditional switch so that three flavors are possible -- minOccurs = "0" for internal clinical use -- minOccurs = "1" for archiving, must contain patient info -- minOccurs = "never" anonymized, must not contain patient info I know that the latter is not possible, that conditionals are not supported in XSL, and that Schematron would be an alternative, but the overhead of the latter seems a large. Note that the conditionals occur in several nesting levels, so that we cannot easily combine versions of a master element with details, but they are always of the type "may", "must", "must not". We would like to avoid having several xsd files and prefer a common file with branching. Any ideas or references to ideas are appreciated.
