But I think FindBugs does some quite deep semantic analysis before
making its suggestions.
I will split "xsl:variable/xsl:value-of" rule in two:
"xsl:variable/xsl:value-of (safe)" will use Saxon API to check type of
XPath expression
"xsl:variable/xsl:value-of (not safe)" will refactor all cases of
xsl:variable/xsl:value-of, assuming human will choose correct
refactorings in file/compare tool
For this refactoring the key information needed to make it safe is not
the type of the expression bound to the variable, but the way in which
the variable is used, which can be analyzed using Saxon's expression
tree - but it's by no means easy.
