Algorithm

Selection

All the <area> tags with a "href" attribute and a "alt" attribute (area[href][alt] )

Set2

All the elements of Set1 with a not empty "alt" attribute

For each element returning false in Test1, raise a MessageA, raise a MessageB instead

Test2

For each element of Set2, we check whether the link content doesn't only contain non alphanumeric characters

For each element returning false in Test2, raise a MessageA, raise a MessageB instead
