> +  Each of these [=/MIME type=]s describe a different [=representation=] of the same [=/clipboard item=] at different levels of fidelity and make the [=/clipboard item=] more consumable by target applications during paste.
+
+  <p class=note>
+   Making the range of cells available as an image will allow the user to paste the cells into a photo editing app, while the text/plain format can be used by text editor apps.
+  </p>
+
+  A [=/clipboard item=] can also optionally have a <dfn>presentation style</dfn> that helps distinguish whether apps "pasting" a [=/clipboard item=] should insert the contents of an appropriate [=representation=] inline at the point of paste or if it should be treated as an attachment.
+
+  Apps that support pasting only a single [=/clipboard item=] should use the first [=/clipboard item=].
+  Apps that support pasting more than one [=/clipboard item=] could, for example, provide a user interface that previews the contents of each [=/clipboard item=] and allow the user to choose which one to paste.
+  Further, apps are expected to enumerate the [=/MIME type=]s of the [=/clipboard item=] they are pasting and select the one best-suited for the app according to some app-specific algorithm.
+  Alternatively, an app can present the user with options on how to paste a [=/clipboard item=], e.g. "paste as image" or "paste formatted text", etc.
+
+  A {{ClipboardItem}} object has an associated <dfn for="ClipboardItem">clipboard item</dfn>, which is a [=/clipboard item=].
+
+  A {{ClipboardItem}} object has an associated <dfn for="ClipboardItem">types array</dfn>, which is a {{FrozenArray}}.

Ah, I understand it now. The `types` are derived from `[=ClipboardItem/clipboard item=]'s [=list of representations=]`. See `getType` algorithm where we fetch the `|itemTypeList|` first from `[=this=]'s [=ClipboardItem/clipboard item=]'s [=list of representations=]`. In Chromium at least, we don't have a separate cache for `types` in the `clipboard item`.
