Steps to reproduce:

I'm not really sure about the correctness or utility of nested DL's. This isn't specifically mentioned in the html spec
or on MDN - DL element but I have included in the example any way since many comments seem to mention it.

Example case

See below or codepen:

Test case

Term 1

Definition text for term 1

Term 2

Definition text for term 2

Term 3

Definition text for term 3

Multi definition term 4

Definition 1 for term 4

Definition 2 for term 4

DL's containing DL's

list item 1

Descriptive of nested list item 1

list item 2

Descriptive of nested list item 2

<h3>Test case</h3>
<dl>
  <dt>Term 1</dt>
  <dd>Definition text for term 1 </dd>
<dt>Term 2</dt>
  <dd>Definition text for term 2</dd>
<dt>Term 3</dt>
  <dd>Definition text for term 3</dd>
<dt>Multi definition term 4</dt>
  <dd>Definition 1 for term 4</dd>
  <dd>Definition 2 for term 4</dd>
<dt> DL's containing DL's</dt>
  <dd>
  <dl>
    <dt>list item 1</dt>
    <dd>Descriptive of nested list item 1</dd>
    <dt>list item 2</dt>
    <dd>Descriptive of nested list item 2</dd>
  </dl>
  </dd>
</dl>

Actual behavior:

Reading in browse mode gives the following text:

heading    level 3  Test case
list  with 11 items  Term 1
Definition text for term 1 
Term 2
Definition text for term 2
Term 3
Definition text for term 3
Multi definition term 4
Definition 1 for term 4
Definition 2 for term 4
DL's containing DL's
list  with 4 items  list item 1
Descriptive of nested list item 1
list item 2
Descriptive of nested list item 2

The I key then only navigates through the DT elements, which is more confusing.

Expected behavior:

Criticisms / expectations collected from comments from this issue and other closed duplicates. Bear in mind this is up for discussion.

• dls are read as lists (i.e. "list"), announce instead "Description List" (prior suggestions were "definition list", however see MDN)
• The item count announced should correspond to the number of dt elements.
• Navigate the list using I, NVDA should announce "Term" for each dt element.
  • Then it is ok if the I key moves from dt to dt element.
• When a dt has more than one dd elements associated with it, announce "Term with definitions"
• The nesting of dls is not announced, parent/child relationships should be expressed.
• Relationships between key-value pairs is not expressed
• It also reports the sum of dt and dd elements as the number of items in the list which is misleading.
