It was interesting to see Mitch Milam's post about the metadata browser. This was a little tool I put together pre-V1.0 ship, but which didn't make the schedule until V3. Mitch points out the "published" component which displays the entity metadata in a nice format. If you edit list.aspx you'll see two sections commented out that provide links to individual entity schemas. This is unsupported and undocumented functionality that we considered calling "sample code". Turns out that it made it into the box but not enabled by default. These schemas work nicely with the code generators that I blogged about a while back.
