I have a collection of documents xml that describes curriculum, but all the documents xml do not have all the fields (or elements), for example a document have the element “postdegree studies” and other no, if I create a scheme for this collection using all the elements that can need a document anyone, can be loaded all documents? or is necessary that all the documents xml have all the elements defined in the scheme.

if the elements are defined as optional (minOccurs=0), this should work
