+  A [=clipboard item=] is conceptually data that the user has expressed a desire to make shareable by invoking a "cut" or "copy" command.
+  For example, if a user copies a range of cells from a spreadsheet of a native application, it will result in one [=clipboard item=]. If a user copies a set of files from their desktop, that list of files will be represented by multiple [=clipboard item=]s.
+  Some platforms may support having more than one [=clipboard item=] at a time on the [=Clipboard=], while other platforms replace the previous [=clipboard item=] with the new one. 
+
+  A [=clipboard item=] has a <dfn>list of representations</dfn>, each <dfn>representation</dfn> with an associated <dfn>mime type</dfn> and <dfn>data</dfn>. In the example where the user copies a range of cells from a spreadsheet, it may be represented as an image (image/png), an HTML table (text/html), or plain text (text/plain).
+  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.
+  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.
+
+  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.

It means to iterate over the mime types. I think this describes how the mime types of a clipboard item are supposed to be processed by a web author so this should be part of the model.
