The DTD used by the DLXS Findaid Class is essentially identical to the EAD2002 DTD. For more information on the EAD2002 DTD, please visit the Library of Congress EAD2002 web site. The only difference is that the dlxsead2002.dtd has one extra element defined that wraps any number ead elements. In this way, we can create a collection of individual ead elements; i.e., a collection of individual finding aids.
