Yup correct.

In Phelbotomy, in order to find the median cubital vein, you'd use the
superficial anatomy of the cubital fossa to identify its borders, such as
the epicondyles of the humerus, then palpate within to find the vein. In
this latter step you'd use characteristics like size, prominence, ability
to refill after depression, and feel of surrounding tissue support, to
identify the right vein. (See below for a more detailed discussion from our
colleagues at Wikidoc).

So in marking up a text describing this procedure, I'd probably tag as
SuperficialAnatomy the palpable landmarks used to identify the vein as well
as the specific characteristics of the vein itself, like size.

Hopefully that helps...I've updated the schema proposal to include a brief
version of this example as well, at
http://schemaorg-medicalext.appspot.com/SuperficialAnatomy

Here's the full writeup from Wikidoc:

"Let’s approach this from the actual anatomical landmark called the cubital
fossa.

The cubital fossa is defined as a triangular area that lies anterior to the
elbow consisting of three borders  (proximal boundary is the medial to
lateral epicondyle of the humerus, medial boundary is the lateral border of
the pronator teres to the medial epicondyle of the humerus, and the lateral
border is the medial border of the brachioradialis originating from the
lateral supraepicondylar ridge of the humerus). The superficial boundary of
the cubital fossa is the skin (or superficial fascia) in which the median
cubital vein, the lateral cutaneous and medical cutaneous nerves of the
forearm rest. The deep boundary of the cubital fossa are the brachialias
and supinator muscles.

In superficial palpation, the cubital fossa can be palpated to find the
brachial pulse (found just medial to the tendon). The brachial pulse is
where you would put your stethoscope for blood pressure measurements.

Now, if you can palpate the borders of the cubital fossa (such as the
epicondyles of the humerus) you will also be able to find the median
cubital vein by palpation of the underlying anatomical structures. A
palpation of a vein for phlebotomy involves feeling the vein for size,
prominence, ability to refill after depression, and feel of surrounding
tissue support."

Great, thanks again for your insightful comments and input!
