There have been more failures, always switching the input from
"pre<!--c1--><?pi arg?><![CDATA[&ent1]]><n2>&deep</n2>post"
to "pre<?pi arg?><![CDATA[&ent1]]><!--c1--><n2>&deep</n2>post".
Using a PATH of node() influences the output. I am not verse unto
XMLTABLE, but could it be an issue where each node is parsed and we
have something like a qsort() applied on the pointer addresses for
each part or something like that, causing the output to become
unstable?
