Summary of Issue: Test procedure Example 4 will not work in all documents
Comment (Including rationale for any proposed change):
In technique PDF 3 the reflow mode is listed as one of the possible testing procedures for 1.3.2, 2.1.1, 2.1.3, 2.4.3.

In PDF for example white text on colored backgrounds very often /mostly the white text isn't visible because the blue background won't be displayed in the reflow-mode. Therefore the test procedure in Example 4 is not working in these situations and for these SCs and testers might come to different / invalid results for example if one tester uses a screenreader and another tester the reflow-mode.

Proposed Change:
Proposed change:

a. Delete example 4 because of the risk of invalid results in evaluations (preferred) or

b. Add a note that this testing procedure should't be used if documents contents white text.
