What is a subject of a test?

When implementing EARL I asked myself "what is the subject of a test" 
and "how many asertions"?

Example:
HTML test document with two images.
Test: look for alt attributes.
Result: None has alt attribute.

Version 1:
One Assertion, one subject (URL of document), one testCase (alt 
attribute test), one result (fail) with two messages (about each of the 
images, including location information)

Version 2:
Two Assertions, each with same subject (URL of document), same testCase, 
one message each (including location information)

Version 3:
Two Assertions, different subject (URL of document + xpointer of error 
instance), same testCase, one message each

Comments?
