    5050\subsection{Branch Mispredictions}
    5151\label{section:XML-branches}
    52 It is hard to handle branch mispredictions in traditional
    53 XML parsers due to: (1) the variable length nature of the syntactic
    54 elements contained within XML documents; (2) a data dependent
    55 characteristic, and (3) the extensive set of syntax constraints
    56 imposed by the XML 1.0/1.1 specifications.
     52In general, performance is limited by branch mispredictions.
     53Unfortunately, it is difficult to reduce the branch misprediction rate of
     54traditional XML parsers due to:
     55(1) the variable length nature of the syntactic elements contained within XML documents;
     56(2) a data dependent characteristic, and
     57(3) the extensive set of syntax constraints imposed by the XML 1.0/1.1 specifications.
    5758% Branch mispredictions are known
    5859% to signficantly degrade XML parsing performance in proportion to the markup density of the source document
