Thank you Andrew. I was not aware of the sibling recursion template.
As I was already using the basic identity transform template, I replaced it
with the modified version, but now some elements are not being copied to the
output. Should it be possible to swap these two templates without re-working
other templates?
Not really because a node that doesn't apply-templates to it's
following sibling will stop the recursion, whereas using the standard
identity the following sibling will get processed because of the
existing apply-templates call that was made from its parent.
For example:
<foo>
<bar/>
<baz/>
<bar/>
</foo>
with a no-op template for baz:
<xsl:template match="baz"/>
Here using the standard identity template both <bar>s will get
processed because of the <xsl:apply-templates/> call when the context
node was <foo>.
However using sibling recursion only the first <bar> is processed from
<foo>, then <baz/> then it stops, so using sibling recursion every
template has a responsibility to process its following sibling.
