The suggestion was not to concatenate $container and $path, it was to
concatenate '$container/' and $path, that is to construct a string
consisting of the string '$container/' followed by (the value of $path
converted to a string); the resulting string will contain an XPath
expression which the evaluate() function then evaluates.
