The pebble tree automaton and the pebble tree transducer are enhanced byadditionally allowing an unbounded number of "invisible" pebbles (as opposed tothe usual "visible" ones). The resulting pebble tree automata recognize theregular tree languages (i.e., can validate all generalized DTD's) and hence canfind all matches of MSO definable patterns. Moreover, when viewed as anavigational device, they lead to an XPath-like formalism that has a pathexpression for every MSO definable binary pattern. The resulting pebble treetransducers can apply arbitrary MSO definable tests to (the observable part of)their configurations, they (still) have a decidable typechecking problem, andthey can model the recursion mechanism of XSLT. The time complexity of thetypechecking problem for conjunctive queries that use MSO definable patternscan often be reduced through the use of invisible pebbles.
