I've got an issue with a project I am working on where individual items or groups of items were digitized with the sponsorship of certain donors. Unfortunately <sponsor> can only come in <titlestmt> and <titlepage> and cannot be placed in the component. Any ideas? Currently I'm using an <odd> with a type attribute with the value "imagesponsor." I suppose a note might work as well, but none of the other component-level elements seem relevant in this case.
