Hi David, all, In the white spaces section we have this PR: "For the elements <sc>, <ec>, <ph> and <data>: The white spaces of their content MUST be preserved in all cases, even if the value for xml:space is set or inherited as default." <sc>, <ec> and <ph> are empty elements and therefore cannot have content, so we shouldn't list them here. Only <data> should be listed here. Cheers, -yves
