MergeIdenticalConditionalBranches
class MergeIdenticalConditionalBranches extends AbstractNormalization
Merge xsl:when branches if they have identical content
NOTE: may fail if branches have identical equality expressions, e.g. "@a=1" and "@a=1"

Methods
Apply this normalization rule to given template
Create an xsl:text element or a text node in current template
No description
Collect consecutive xsl:when elements that share the same kind of equality tests
Merge identical xsl:when elements from a list
Inspect the branches of an xsl:choose element and merge branches if their content is identical and their order does not matter
Inspect the branches of an xsl:choose element and merge consecutive branches if their content is identical
