How many scheme & host tags can come under intent-filter in android manifest

Need more info regarding intent-filter tag specified in manifest. I am aware that we can specify data in two forms:

<intent-filter>
     <data android:host="com.myHost" android:scheme="content"/>
</intent-filter>

AND :

<intent-filter>
     <data android:scheme="content"/>
     <data android:host="com.myHost"/>
</intent-filter>

But I wish to know can several combinations exist, like

<intent-filter>
         <data android:host="com.myHost" android:scheme="content"/>
         <data android:scheme="content"/>
         <data android:host="com.myHost1"/>
</intent-filter>

OR:

<intent-filter>
         <data android:host="com.myHost" android:scheme="content"/>
         <data android:scheme="content"/>
         <data android:host="com.myHost1"/>
         <data android:scheme="content"/>
         <data android:host="com.myHost2"/>
</intent-filter>

In the last case, I wish to know firstly if this can exist & how is it decided that which host to be used for which scheme, as the data tags containing scheme & host can occur in any order.

Please help.
