Documentation states that parameter 11 in report declarative BLOB format masks is used as the <tt>alt</tt> attribute for the generated <tt>img</tt> element. However no <tt>alt</tt> attribute is in fact generated (examples).
This is a significant issue as <tt>alt</tt> is a required attribute for <tt>img</tt> elements.

Originally reported for APEX 4.0.2, the <tt>alt</tt> attribute is still missing in 4.2.
