I'm submitting a ... (check one with "x")

Current behavior
With RC5 it's working fine.
With RC6: Error: Only selectors matching element names are supported, got: [alertManagerRow].

Reproduction of the problem

Please provide a way to implement it, as you can see in the plunkr, it cannot be used as a non-attribute definition.

Please tell us about your environment:

• Angular version: 2.0.0-rc.6
• Browser: [all ]
• Language: [TypeScript 2.0.2 | ES5 | SystemJS ]

Regardless if it is antipattern or not it should not be upgrade making the check. I will have a look and should have a PR shortly.

@vicb let us know if you need any more details

Looking at the code, this issue seems to have been introduced by this commit
4a740f2

                ._bootstrapModuleWithZone(
                     DynamicNgUpgradeModule, undefined, ngZone,
                     (componentFactories: ComponentFactory<any>[]) => {
                       componentFactories.forEach((componentFactory) => {
                         componentFactoryRefMap[getComponentInfo(componentFactory.componentType)
                                                    .selector] = componentFactory;
                       });
                     })

_bootstrapModuleWithZone is now called with a callback which is, according to the comment left in the code, an ugly internal api hack :)

// ugly internal api hack: generate host component factories for all declared components and
 // pass the factories into the callback - this is used by UpdateAdapter to get hold of all
 // factories.

the fix is in 2.0.1

Current behaviour
With RC6 using ngUpgrade we cannot create directives like this:

@Component({
  selector: '[alertManagerRow]',
  template: `
  <td>foo</td>
  <td>bar</td>
  `
})

Use case:

<table>
        <thead>
          <tr>
            <th>1st column</th>
            <th>2nd column</th>
          </tr>
        </thead>
        <tbody>
          <tr alertManagerRow [number]="777"></tr>
          <tr alertManagerRow [number]="333"></tr>
        </tbody>
      </table>

Error: zone.js:461 Unhandled Promise rejection: Only selectors matching element names are supported, got: [alertManagerRow] ; Zone: ; Task: Promise.then ; Value: Error: Only selectors matching element names are supported, got: [alertManagerRow]

With RC5 was working perfectly.

Expected behaviour
Rendering of directive without any error. As it works without using ngUpgrade. It was working in RC5.

Steps to reproduce
Just see console error in this plunkr: http://plnkr.co/edit/ImXKSq0EOM80kVtaJVpQ?p=preview
