+problem: sometimes you want to have attachments in a certain order, but `attachment` is an unordered set by default
+
+solution: define `orderedAttachment` similar to `orderedItems`
+
+```json
+{
+	"@context": [
+		{
+			"orderedAttachment": {
+				"@id": "https://...",
+				"@type": "@id",
+				"@container": "@list"
+			}
+		},
+		"https://www.w3.org/ns/activitystreams"
+	]
+}
+```

+you could maybe do the same for `orderedTag` but idk if that makes full sense bc `tag` is not really used for categorization so much... but if tumblr or a tumblr-like implementation wanted to order their tags then they have no way of doing so
