Vista - About ToolBar's Band and BandIndex Properties

Hello,

Although this is not a technical help request, I wonder if someone (from
Microsoft or not) can think of a reason for the fact that the Band and
BandIndex properties of a ToolBar object are simple dependency properties and
not depdendency properties attached to ToolBarTray.

If I think about Band and BandIndex which are defining the "row" and
"column" in a horizontal ToolBarTray I don't see a reason for using the Band
and BandIndex properties if the ToolBar was not inside of a ToolBarTray...
They should be, in my opinion, attached properties, like DockPanel attaches
the Dock property, or as Grid attaches the Row and Column properties for the
inner elements.

Maybe however there are good reasons for these not being implemented this
way in the current version of WPF, but I assume someone could at least
explain those reasons to me and others like me, who like the principles of
WPF but don't like when some types of WPF itself don't follow the rules...

I already talked about this with somebody on the Microsoft's WPF Forum, and
I got the suggestion that maybe the two properties are set to the ToolBar
object rather than attached to the ToolBarTray because we can have only
toolbars in a tray.

But however, then I need to ask why there is an attached IsLocked property
of ToolBarTray (which works for ToolBars in the tray only), instead of
creating an IsLocked property on the ToolBar itself (in the same manner)? I
doubt therefore that this is the real reason and I came to ask here also.
