<!--
Tests here consist of isEqualNode comparisons of the first and third
(zero-indexed) child nodes of each test.
In the typical case this means that the zeroth, second, and fourth
children are whitespace and the first and third are the nodes being
compared for equality or inequality.
In some cases, however, where either node is a Text node, this pattern
must of necessity be violated. Examples of such tests include the
test_text# tests.
As a result of this, BE CAREFUL NOT TO INTRODUCE STRAY WHITESPACE WHEN
EDITING THIS FILE. You have been warned.
