+<!--
+This file holds serialized tests for DOM Range tests on extractContents.
+The <test/> elements designate individual tests.  Each one has the following:
+
+* A <source/> element, designating the start conditions of the test,
+* A <result/> element, designating what the source element should look like
+  after the extraction,
+* An <extract/> element, designating what the extracted content should look like.
+
+The <split/> element designates a split between two DOM nodes. This element will
+be removed before the actual test, and the two nodes on either side will not be
+merged.
+
+The <empty-cdata/> element designates an empty character data section.  Before
+the test executes, this element is replaced with an actual CDATASection node.
+
+For the <source/> element, there are four attributes:
+
+* startContainer:  A XPath to the startContainer of the range.
+* endContainer:  A XPath to the endContainer of the range.
+* startOffset:  The startOffset of the range.
+* endOffset:  The endOffset of the range.
+
+Note this test may need updating with a fix for bug 401276.  The spec states
+adjacent nodes after an extraction should be merged if possible, but using the
+normalize() method, which could have unintended side effects... For now, we're
+not permitting that, pending clarification.
+
+Please make sure the first test in this document always tests a range where the
+start container and end container are the same text node, and where the start
+offset and end offsets are valid and inequal.  Some of the additional range
+tests (after the bulk of the delete/extract tests) depend on it.
