Steps to reproduce:

1. Install MathCAT from the addon store
2. Open attr-ex.pdf in Adobe Reader. The first bit of math looks like:

3. Arrow to the first equation.The first expression has an "intent" attributes that should cause the speech to say something like " 2 lines line 1 with label 1 ... line 2 with label 2 ..."

Actual behavior:

The speech is:
2 lines line 1 eigh is equal to b c is equal to d line 2 b is equal to 2 d is equal to 3

Expected behavior:

The speech is:
2 lines line 1 with label 1 eigh is equal to b c is equal to d line 2 with label 2 b is equal to 2 d is equal to 3

Note: this assumes the speech style is ClearSpeak. If the speech style is SimpleSpeak, the actual behavior is the same but the expected behavior will use "equation" instead of "line" due to the intent attribute value ":system-of-equations" on mtable.
