-Each target attribute is [a set of space separated IDs][], each of which is the ID of an element, that is a [`cell`][] of the same [`table`][].
+Each target's [attribute value][] is a [set of space separated tokens][]. Each token is the value of the `id` attribute of an element, that is a [`cell`][] of the same [`table`][].
**Note:** `headers` attribute referencing elements that are non-existent or not in the table are ignored when [assigning header cells (step 3, first case, point 2)](https://html.spec.whatwg.org/multipage/tables.html#algorithm-for-assigning-header-cells).
## Expectation 2
-Each target attribute is [a set of space separated IDs][], none of which is the ID of the element on which the test target is specified.
+Each target's [attribute value][] is a [set of space separated tokens][], and none of these tokens is the `id` of the element on which the test target is specified.

## Assumptions
- This rule assumes that the `headers` attribute is only used to identify table headers. If other information is included in the `headers` attribute, the rule may fail on issues that are not accessibility concerns. For example, if `headers` is used to include information for scripts, this rule may not be accurate.
-- This rule assumes that the `headers` attribute is required to express the relationship between data and header cells in the `table`. If the browser [computes an adequate fallback header][], this rule may produce incorrect results.
+- This rule assumes that the `headers` attribute is required to express the relationship between data and table header cells in the same `table`. If the browser [computes an adequate fallback header][] for cells that have the `headers` [attribute value][] that does not correspond to the `id` of any one cell in the same `table`, success Criterion [1.3.1 Info and Relationships][sc131] may be satisfied even if this rule failed.
