Dear Interest Group,

I am proposing new rules for the 508 Refresh that could included in WCAG
2.0 without changing normative.  They involve adding three fail cases.  It
would be a shift for WCAG WG members who do not recognize color and text
level presentation as being capable of interfering with information,
relationships,  structures or correct reading sequence.  The simple fact is
that rigid content structures that prevent reasonable change to these
parameters are the largest single obstetrical to visual access for people
with low vision.  The link below gives the text of my second comments to
the Access Board. I am proposing these changes.  The Access Board can adopt
them as additional with no change to WCAG 2.0. Should the W3C decide the to
change  the Techniques document everything can stay in total harmony.


It is good reading including my definition of data table.
A data table is a table that defines a partial function from order pairs of
rows and columns into a space of data values.

Compared with layout tables a data table cannot be linearized without
losing the partial function relation.
