Hi all, I am new to EAD with no practical experience at all, so my question is probably an illiterate one. In preparation of an inventory for an outsource encoding I am marking <c> elements with the level numbers. The description is performed on the file level (file = folder). My question is, can I, within the same <c03> level (sub-subseries), among <c04>s for file level mark with <co4> a group of files, with <c05>s for individual files within this group? The structure will look like this: <c01>[Series] <co2>[Subseries] <c03>[Sub-subseries] <c04>[File] <c04>[File] <c04>[Group of files] <co5>[File] <c05>[File] <c04>[File].... </c04></c03></c02></c01> Thanks for your help.
