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. |
