HTML tags with attributes that have link semantics

Static analysis of HTML pages for harvesting links in the code should not necessarily focus on href attributes of anchor tags. Here's a short list of attributes that take a URI as a value along with their HTML tag names:

Tag Name	Attribute Name
a	href
img	src
script	src
iframe	src
base	href
form	action
link	href
input	usemap
input	src
head	profile
frame	src
frame	longdesc
