| Abstract(in English) | This paper demonstrates a new subclass of DTDs, called DC/DF-DTDs, under which XPath satisfiability with child, descendant-or-self, and sibling axes becomes tractable. DC/DF-DTDs are defined as a "hybrid" of two known tractable classes, duplicate-free DTDs and disjunction-capsuled DTDs, and are a proper superclass of them, provided that operators "?" (zero or one occurrence) and "+" (one or more occurrences) are disallowed. This paper also shows that parent axes or qualifiers bring intractability to XPath satisfiability under DC/DF-DTDs. |
