/*********************************************************************

|
* carry out accessibility checks
|
|
*
|
|
* This module carries out processes for all accessibility checks. It
|
|
* traverses through all the content within the tree and evaluates the
|
|
* tags for accessibility.
|
|
*
|
|
* To perform the following checks, 'AccessibilityChecks' must be
|
|
* called AFTER the tree structure has been formed.
|
|
*
|
|
* If, in the command prompt or configuration file, there is no
|
|
* specification of which accessibility priorities to check, then no
|
|
* accessibility checks will be performed.
|
|
*
|
|
* The accessibility checks to perform depending on user's desire:
|
|
* 1. priority 1
|
|
* 2. priority 1 & 2
|
|
* 3. priority 1, 2, & 3
