+the display contrast. </shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>
+<p>A base port must define the attributes that clients can use on a phone,
+and implement any functions that are required to get and set the attributes.</p>
+<p id="GUID-4DA41221-40B9-5BC7-B2C6-7C6EB4522508"> To define attributes, you
+must change the source of the <filepath>hal.dll</filepath> library and rebuild
+it. Functions that get and set attributes are implemented as HAL handler functions
+in kernel-side programs, for example, device drivers. </p>
