I am trying to add schema.org markup to a chiropractic website. My issue is how to determine which markup to use so our site will show more helpful SERPs when patients are looking for information regarding symptoms/treatment. 

Our website manager has a bunch of crazy HTML and I'm plugging in the schema markup I want within existing code. Do you have to use the `<body>` tags or can the `itemscope` and `itemtype` show in `<p>` tags? 

I'd like to use this markup for the page describing prenatal chiropractic care: 

```html
<body itemscope itemtype="http://schema.org/MedicalWebPage">
<link itemprop="audience" href="http://schema.org/Patient"/>
<link itemprop="specialty" href="http://schema.org/Obstetric"/>

```

Is this the best way to implement the markup? I didn't see a specialty for chiropractic or I would have put it there instead of Obstetric.
