Using <break> tag in SSML Text to Speech

Hello all, I am excited to use the SSML feature. I am specifically trying to add a few pause breaks using the Danielle voice. I am using the <break> tag but keep getting the error stating 'Storyline 360 can't convert this text to speech. Verify the SSML tags are correct and supported for the selected voice.' Where am I going wrong?

This is what I have for Danielle:

<speak>
Now that you have reviewed the IT Expense Management Guide, let’s discuss the project work flowchart.
<break>
Begin by asking yourself <break>‘is this project work’?
If yes, <break>Is it Strategic, <break>Operational, <break> or New Development? <break>
If no, <break> is it Production Issue Resolution? <break>
If no <break> is it Fee-for-service? <break>
If no, <break> then it is Departmental.
