+
+Adds a filter-for-export filter:
+
+This formatter walks through the content tree.
+
+At each node it checks if the node implements a method `filterForExport`
+
+If so, the method is called.
+
+In this way, custom elements can filter out their contents from export.
+
+So if an editor includes an element: `<custom-element></custom-element>`,
+
+And the custom element sets some content such that inner html looks like:
+
+`<custom-element>Content For Display</custom-element>`
+
+The prototype for `<custom-element>` may implement `filterForExport` thusly:
+
+```
+CustomElement.prototype.filterForExport = function () {
+  this.innerHTML == '';
+  }
+```
+
+And the exported html will look like this:
+
+`<custom-element></custom-element>`
+
+In this way a custom element my render demonstrative content inside the editor,
+but not have that content saved to our database.
