 But if the answer is yes, then we violate the canonical constraint since any permutation of characters having an align attribute would represent the same content.

 It is not clear if our resulting line is aligned center or right. We could delete both or have some ordering rule to favor one over the other, but our Delta is becoming more complex and harder to work with on this path.

 To solve this, Quill "adds" a newline to all documents and always ends Deltas with "\n".

 #### Delete
 
-To describe deleting text, we need to know where and how many characters to delete. To delete embeds, there needs not be any special treatment, other than to understand the length of an embed. If it is anything other than one, we would then need to specify what happens when only part of an embed is deleted. There is currently no such specification, so regardless of how many pixels make up an image, how many minutes long a video is, or how many slides are in a deck; embeds are all of length _one_.

 One reasonable way to describe a deletion is to explicitly store its index and length.

 The special case is when we want to remove formatting. We will use `null` for this purpose, so `{ bold: null }` would mean remove the bold format. We could have specified any falsy value, but there may be legitimate use cases for an attribute value to be `0` or the empty string.
 
-**Note:** We now have to be careful with indexes at the application layer. As mentioned earlier, Deltas do not ascribe any inherent meaning to any the `attributes`' key-value pairs, nor any embed types or values. Deltas do not know an image does not have duration, text does not have alternative texts, and videos cannot be bolded. The following is a **legal** Delta that might have been the result of applying other **legal** Deltas, by an application not being careful of format ranges.

 Since every character is described, explicit indexes and lengths are no longer necessary. This makes overlapping ranges and out-of-order indexes impossible to express.
