-Caveats
--------
+False-positives
+---------------
 
-There is no support yet for testcases which are expected to fail.
+Most of the time, the input can be tweaked so that all warnings bookloupe
+reports represent real errors in the text. Sometimes, however, this either
+cannot be done and still test what we need to. In these cases we need a
+means to describe these false-positives (warnings that do not describe
+a real error). This is important so that a later version of bookloupe can
+be improved to not issue the false-positive warning and still pass the
+test. In order to do this, we need to describe the warnings in a more
+structures manner, like this:

+Here, we use the "WARNINGS" tag instead of "EXPECTED" to denote that we
+wish to use structured warnings and the list of warnings is enclosed in
+an <expected> ... </expected> node.
+
+Each warning, or potential warnings is then described using either an
+"error" node (for warnings that represent real errors in the text), a
+"false-positive" node (for warnings that do not represent real errors),
+or a "false-negative" node (for warnings that should be issued, but that
+are not yet detected by bookloupe).
+
+Within each warning node, there are then one or more "at" nodes which
+list the acceptable locations for the warning to be reported at (the
+first listed should be the preferred location) and exactly one "text"
+node which must match the text of the warning issued.
+
+A testcase will pass if all the warnings marked as errors were issued and
+if no warnings were issued that are not listed in one form or another.
+If the testcase passes with an expected failure (ie., issues a warning
+for a false positive or does not issue a warning for a false negative),
+then the test is counted as passed, but a note will be printed describing
+this, eg.:
+
+sample: PASS (with 1 of 1 false positives and 1 of 1 false negatives)
