Abstract
Techniques are provided for performing focus inference when compiling an Extensible Markup Language Transforms (XSLT) stylesheet into a compiled XSLT processor. In XPath/XSLT, expression evaluation occurs with respect to the dynamic context. In XPath, the part of the dynamic context, related to the context node-set, is called the 'focus' of the expression. Conceptually, the focus would need to be systematically computed and propagated along the recursive execution of XSLT templates. This is costly. Focus inference enables the more efficient execution of XSLT programs since the inferred focus information can be used directly by a code generator in an XSLT compilation architecture.
