In our previous work, we proposed RW-DTDs, which cover most of the real-world DTDs (26 out of 27 real-world DTDs and 1406 out of 1407 DTD rules). However, under RW-DTDs, XPath satisfiability with only child, descendant-or-self, and sibling axes is tractable. In this paper, we propose MRW-DTDs, which are slightly smaller than RW-DTDs but have tractability on XPath satisfiability with parent axes or qualifiers.
