I put some time into that over the week. The code now includes maps of expected attributes (per DIE tag), and expected forms (per attribute form). Attributes are checked by recursive iteration of the DIE tree. That approach will be necessary for checking expected children, but attributes, I think, would better be checked from abbreviations. But I don't think that <dwarf> provides support for that. Attribute form is not checked, because there's no way to obtain that from <dwarf>. So the table is here, but it's not being used currently. I've also written this to DwarfLint wiki page. PM
