Partial layouts

[miensol]

It seems it would be a nice to be able to reuse some partial layouts and be able to use them inside parent layout like so. Questions:

• which syntax is better?

  <UIView>
  <include src="LayoutName" /> <!-- It seems clear that we can't use id here -->
  </UIView>

  or

  <UIView>
  <LayoutName id='idIsPossible' />
  </UIView>

  The latter seems nicer to me, however there are some issues with including partial that has no single root - see below.

• is it worth the trouble to support partials with multiple root elements defined? In other words a partial like this:

  <UIView id="leftColumn" />
  <UIView id="rightColumn" />

  if so then using partial name instead of include element makes using id a bit inconsistent. Unless there is some clever way of handling it

A working implementation is in place with following syntax:

<include layout="BrightLogo"/>
