-The `core-style` element helps manage styling inside other elements and can 
-be used to make themes. The `core-style` element can be either a producer 
-or consumer of styling. If it has its `id` property set, it's a producer. 
-Elements that are producers should include css styling as their text content.
-If a `core-style` has its `ref` property set, it's a consumer. A `core-style`
-typically sets its `ref` property to the value of the `id` property of the
-`core-style` it wants to use. This allows a single producer to be used in 
-multiple places, for example, in many different elements.
-
-It's common to place `core-style` producer elements inside HTMLImports.
-Remote stylesheets should be included this way, the &#64;import css mechanism is
-not currently supported.
-
-Here's a basic example:
-
-    <polymer-element name="x-test" noscript>
-      <template>
-        <core-style ref="x-test"></core-style>
-        <content></content>
-      </template>
-    </polymer-element>
-
-The `x-test` element above will be styled by any `core-style` elements that have
-`id` set to `x-test`. These `core-style` producers are separate from the element
-definition, allowing a user of the element to style it independent of the author's 
-styling. For example:
-
-    <core-style id="x-test">
-      :host {
-        backgound-color: steelblue;
-      }
-    </core-style>
-
-The content of the `x-test` `core-style` producer gets included inside the
-shadowRoot of the `x-test` element. If the content of the `x-test` producer
-`core-style` changes, all consumers of it are automatically kept in sync. This
-allows updating styling on the fly.
-
-The `core-style` element also supports bindings and it is the producer 
-`core-style` element is the model for its content. Here's an example:
-
-    <core-style id="x-test">
-      :host {
-        background-color: {{myColor}};
-      }
-    </core-style>
-    <script>
-      document._currentScript.ownerDocument.getElementById('x-test').myColor = 'orange';
-    </script>
-
-Finally, to facilitate sharing data between `core-style` elements, all
-`core-style` elements have a `g` property which is set to the global 
-`CoreStyle.g`. Here's an example:
-
-    <core-style id="x-test">
-      :host {
-        background-color: {{g.myColor}};
-      }
-    </core-style>
-    <script>
-      CoreStyle.g.myColor = 'tomato';
-    </script>
-
-Finally, one `core-style` can be nested inside another. The `core-style`
-element has a `list` property which is a map of all the `core-style` producers.
-A `core-style` producer's content is available via its `cssText` property. 
-Putting this together:
-
-    <core-style id="common">
-      :host {
-        font-family: sans-serif;
-      }
-    </core-style>
-
-    <core-style id="x-test">
-      {{list.common.cssText}}
-
-      :host {
-        background-color: {{g.myColor}};
-      }
-    </core-style>
