Alternative for supporting a control set style

Title: 

As the conversation this morning was generally negative concerning adding
additional CSS styles that could represent  a set of mode controls I offer
the following solution in lieu of working through a detailed design for something
that will likely be rejected anyway.  Basically, the solution focuses on
communicating to the portlet "layout" information that a portlet could then
use to make UI decisions.  Passing such information is optional.  Using the
information is optional.  However, portals that choose to pass such information
can at least be ensured that the subset [hopefully large] that take it into
consideration will yield a consistent UI within the portal.  The argument
for including this "special" layout information continue to be that our specification
forces the portlet to render these controls however the consumer/portal has
a vested interest in establishing a consistent L/F for these controls.

Solution:

Add the following optional field to MarkupParms:

[O] ModeControlLayout  modeControlLayout

where ModeControlLayout is:

ModeControlLayout

     [R]  Controls controls[]

     [O]  ControlOrientation  controlOrientation

     [O]  ControlAlignment controlAlignment

Where Controls, ControlOrientation and ControlAlignment are restrictions
on the string type that are contrained to specific values:

    Controls: "apply", "cancel", "ok", "reset", "previous", "next"

    ControlOrientation: "top", "bottom"

    ControlAlignment: "left", "center", "right"

Members:

  
controls: This array defines the type and order of controls
the portlet should use to be consistent with the Look/Feel for this consumers
Mode controls.  Portlets wishing to be consistent will render such controls,
inconjunction with the other layout rules, preferrably by using WSRP predefined
styles corresponding to these controls.

  
controlOrientation: The value of this field tells the portlet
the consumers preferred orientation for the controls mentioned above.  An
orientation of "top" indicates a desire that the controls appear at the top
[or first] of the modes rendition.  An orientation of "bottom" indicates
a desire that the controls appear at the bottom [or last] of the modes rendition.

  
controlAlignment:  The value of this field tells the portlet
how the consumer prefers the portlet align the controls mentioned above.
 A "left" alignment indicates a desire the controls be rendered flush left
with respect to the overall content/form.  A "center" alignment indicates
a desire the controls be rendered centered with respect to the overall content/form.
 A "right" alignment indicates a desire the controls be rendered flush right
with respect to the overall content/form.
