approved.

Should this now be showing up in the reference, and have nav pane
entries?

Um, no, because this is one of those magic things that has no representation in the LFC. I guess if you point me to where the documentation for the <class> tag is, I could use that as a guide and make a similar page for <mixin>. Thanks!

There is no doc for the <class> tag; that's another bug:

Summary: First pass at <mixin>

New Features: <mixin>

Bugs Fixed:
LPP-2302  Implement LZX <mixin> tag
LPP-7365 Update color names to use CSS3 standard

Technical Reviewer: max (pending)
QA Reviewer: hminsky (pending)
Doc Reviewer: [EMAIL PROTECTED] (pending)

Documentation:

 <mixin> is like <class> but rather than creating something you can
 instantiate, creates a template that can be 'mixed in' (added to)
 more than one other class.  A <mixin> is like an interface, but it
 is allowed to have state and implementation.

 <mixin> is an advanced feature.  To add a mixin to a class you
 say:

 <class name="icecream" ... />
 <class name="walnuts" ... />

 <mixin name="toppings">
   <attribute name="sauce" type="color" value="lavender" />
   <attribute name="whippedcream" type="boolean" value="true" />
   <attribute name="cherry" type="boolean" value="true" />
   ...
 </mixin>

 <class name="sundae" extends="icecream" with="toppings />

 <sundae name="chocfulla"
   flavor="honeydew"
   sauce="lemonchiffon">
   <walnuts ground="true" />
 </sundae>

 See tests/classes.lzx for a more complete example

Details:
 test/classes: Create a more complex example using classes and
 mixins

 lfc-undeclared: Add <mixin>

 LzConstants, ViewSchema: Update color tokes to CSS3 standard

 ClassCompiler: Learn how to create interstitial <nodes>, insert
 them into the schema.

Compiler, MixinCompiler: For now, just compiles the mixin as a class.

 NodeModel: Only classes can have `extends` or `with` attributes.

 ElementWithLocationInfo: Support cloning of elements (to make
 mixin interstitials).
