+There are three extensions in various versions:
+
+1  version_XXX/plain.oxt has no dependencies and no license.
+2a version_XXX/dependency.oxt has an unsatisfied dependency and no license.
+2b version_nodependencies_XXX/dependency.oxt is identical to 2a but without the
+   dependency.
+3  version_XXX/license.oxt has no dependencies and a license.
+
+The different versions are:
+
+A  version_none contains no version element (treated as version "0").
+B  version_badelement contains a bad <version val="1"/> (not allowed by the
+   specification, but treated by the current implementation as version "0").
+C  version_badvalue contains a bad <version value="1.a"/> (not allowed by the
+   specification, but treated by the current implementation as version "1").
+D  version_0.0 contains <version value="0.0"/> (same as version "0").
+E  version_1.2.3 contains <version value="1.2.3"/>.
+F  version_1.2.4.7 contains <version value="1.2.4.7"/>.
+G  version_1.02.4.7.0 contains <version value="1.02.4.7.0"/> (same as version
+   "1.2.4.7").
+H  version_1.2.15.3 contains <version value="1.2.15.3"/>.
+
+The total order among the various versions is thus
+
+  A = B = D < C < E < F = G < H.
+
+Things to watch for:
+
+- If version y of extension e is to be installed and version x < y of
+  extension e is already installed, then
+   unopkg add e
+  will replace x with y.
+
+- If version y of extension e is to be installed and version x >= y of
+  extension e is already installed, then
+   unopkg add e
+  will fail with an error message.
+
+- If version y of extension e is to be installed and any version x of
+  extension e is already installed, then
+   unopkg add -f e
+  will replace x with y.
+
+- If version y of extension e is to be installed and any version x of
+  extension e is already installed, then
+   unopkg gui "Add..."
+  and
+   soffice "Tools - Package Manager... - Add..."
+  will query with a dialog whether to replace x with y.  The dialog will have
+  "OK" (replace) preselected if x < y, and "Cancel" otherwise.
+
+- If replacing an installed version x of an extension e with a version y fails
+  because y has unsatisfied dependencies, or because y has a license to which the
+  user does not agree, version x is left installed afterwards.
+
+- Checking for already installed versions of an extension is only done within a
+  single layer (unopkg versus unopkg --shared; "My Packages" versus
+  "OpenOffice Packages" in unopkg gui/soffice), not across layers.
