+Defining Widget Elements
+========================
+
+Widget type
+-----------
-* `mkwsSearch` -- provides the search box and button.
+An HTML element is made an MKWS widget by including an MKWS
+class-name. These names begin `mkws-`: what follows that prefix
+specifies the type of the widget. The type can be any sequence of
+alphanumeric characters and hyphens _except_ something beginning
+`team` -- see below.
-* `mkwsResults` -- provides the results area, including a list of
+The main widgets are:
+
+* `mkws-search` -- provides the search box and button.
+
+* `mkws-results` -- provides the results area, including a list of
brief records (which open out into full versions when clicked),
paging for large results sets, facets for refining a search,
sorting facilities, etc.
-* `mkwsLang` -- provides links to switch between one of several
- different UI languages. By default, English, Danish and German are
- provided.
+* `mkws-progress` -- shows a progress bar indicating how many of the
+ targets have responded to the search request.
-* `mkwsSwitch` -- provides links to switch between a view of the
+* `mkws-stat` -- provides a status line summarising the statistics of
+ the various targets.
+
+* `mkws-switch` -- provides links to switch between a view of the
result records and of the targets that provide them. Only
meaningful when `mkwsTargets` is also provided.
-* `mkwsTargets` -- the area where per-target information will appear
+* `mkws-targets` -- the area where per-target information will appear
when selected by the link in the `mkwsSwitch` area. Of interest
mostly for fault diagnosis rather than for end-users.

- the various targets.
+* `mkws-lang` -- provides links to switch between one of several
+ different UI languages. By default, English, Danish and German are

+
+Widget team
+-----------
+
+In general a set of widgets work together in a team: in the example
+above, the search-term that the user enters in the `mkws-search`
+widget is used to generate the set of records that are displayed in
+the `mkws-results` widget.
+
+Sometimes, it's desirable to have multiple teams in a single page. A
+widget can be placed in a named team by giving it (in addition to its
+main class) a class that begins with `mkws-team-`: what follows that
+prefix specifies the team that the widget is part of. For example,
+`
` creates a search widget that
+is part of the `aux` team.
+
+Widgets that do not have a team specified (as in the examples above)
+are placed in the team called `AUTO`.
+Old and new-style class-names
+-----------------------------
+
+**NOTE.** Versions of MKWS before v1.0 used camel-case class-names:
+without hyphens and with second and subsequent words capitalised. So
+instead of `mkws-search`, it used to be `mkwsSearch`. And the classes
+used to specify team names used an `mkwsTeam_` prefix (with an
+underscore). So instead of `mkws-team-foo`, it used to be
+`mkwsTeam_foo`.
+
+The 1.x series of MKWS releases recognise these old-style class-names
+as well as the canonical ones, as a facility for backwards
+compatibility. However, **these old class-names are deprecated, and
+support will be removed in v2.0**. Existing applications that use them
+should be upgraded to the new-style class names as soon as convenient.
Configuration
=============
Many aspects of the behaviour of MKWS can be modified by setting

+`facet-subjects` rather than `facet`. (So `class="mkws-template-facet-subjects"`)
You can also explicitly specify a different template for a particular instance
of a widget by providing the name of your alternative (eg. SpecialPager) as the
value of the `template` key in the MKWS config object for that widget:
