Decision level
Semi-Decidable
Algorithm
Selection
Set1 (table tags identified as complex table from html markers)
All the <table> tags with an id attribute or a class attribute or a role attribute that matches one of the
values set by the user through the “PRESENTATION_TABLE_MARKER” parameter.
Set2 (table tags not identified as complex table from html markers)
All the <table> tags that don’t have an id attribute or a class attribute or a role attribute that matches one
the values set by the user through the “PRESENTATION_TABLE_MARKER” parameter or the “DATA_TABLE_MARKER” parameter or the
“COMPLEX_TABLE_MARKER” parameter. That means select all the <table> tags of the page when these parameters are empty.
Process
Test1
For each element of Set1, raise a MessageA.
Test2
For each element of Set1, test whether the role attribute is present with a value equals to “presentation”.
For each element returning true in Test2, raise a MessageB.
Test3
For each element of Set2, raise a MessageC.
Test4
For each element of Set2, test whether the role attribute is present with a value equals to “presentation”.
For each element returning true in Test4, raise a MessageD, raise a MessageE instead.

Analysis
Not Applicable
The page has no <table> tags or only tables identifed as data or complex tables (Set1 AND Set2 are empty)
Failed
The role attribute with the “presentation” value is missing on at least one presentation table (Test2 returns
false for at least one element)
Pre-qualified
In all other cases
