---------------
*Increments*
I'm afraid that below isn't specific enough and you need to say
something about specific values  &/or increments.

SH01) * Current text: "Line spacing, choosing from a range with at least 
three values"
As it is written, a user agent that provided 1.0, 1.1, 1.2 would meet
this criteria; however, that doesn't meet the needs of most users who
need increased line spacing, as most need between 1.25 and 2.0.

UAWG changed 1.4.1 * Line spacing to
* Line spacing, choosing from a range with at least three values up to 
at least 2 times the default
http://w3c.github.io/UAAG/UAAG20-Reference/#sc_141
UAWG added Note 4 to the introduction of 1.4:
Note 4: When it comes to magnification, size, or spacing, the optimum 
value for a given user would vary based on their visual impairment and 
the size of the content they’re reading. Therefore it’s recommended that 
user agents provide a wider range of values, and a greater number of 
increments, to allow the user to adjust the view for their current task.
UAWG added a sentence to the Intent of 1.4.1:
http://w3c.github.io/UAAG/UAAG20-Reference/#sc_141-i
At a minimum, it is recommended to offer line spacing options of 1, 
1.25, 1.5 and 2.0.


SH02) * Current text: "1.8.5 Allow Zoom:  The user can rescale content 
within
top-level graphical viewports as follows: (Level A) Zoom in: to 500% or
more of the default size..."
As it is written, a user agent that provided just two options for zoom:
100% and 500%, would meet this criteria; however, that's not
sufficiently accessible because the vast majority of users who need zoom
will need it at a percent in between 100 & 500%.

UAWG does not accept the comment because this is already well 
implemented, the UA already have nearly infinite zoom up to 500%. UAAG 
wording is agnostic and allows UAs to use what ever method to provide 
the scaling to 500%

SH03) * Current text: "Character spacing, choosing from a range with at 
least 5 values"
This may have the same issue as above, although maybe not because the
range of character spacing needed is far less, afaik.

UAWG added a sentence to UAAG Reference: "It is recommended to provide a 
range of character spacing of at least 0.01, 0.03, 0.06, 0.09 times the 
base character width. "
http://w3c.github.io/UAAG/UAAG20-Reference/#sc_143-i

SH04) *Inconsistencies*
I'm not sure if the inconsistencies below are on purpose or in error? :-)

* 1.4.1 Basic text formatting (Globally):… Text scale with…
     1.4.2 Basic text formatting (by Element): … Text size or scale

* 1.4.1 Basic text formatting (Globally):…
	Text color and background color, choosing from all platform color options
	Font family, choosing from all installed fonts [this says "installed" &
others say "platform"]
1.4.2 Basic text formatting (by Element):
	Text color and background color, choosing from all platform color options
	Font family, choosing from at least all platform fonts

UAWG choose the wording with care.  Globally, text is scaled, but by 
element it can be sized or scaled.   Fonts are installed, but colors are 
chosen from the platform.  We reviewed the other success criteria to 
make sure the wording was consistent.

  *missing*

SH05) "Text style (underline, italic, bold)"
Current text has it only provided by Element; it is missing from Globally.

UAWG added a bullet to 1.4.1: Text style, choosing to turn on/off 
underline, italic, bold
http://w3c.github.io/UAAG/UAAG20/#sc_141


SH06) * I had suggested more element-level customization at Level AAA 
that is missing from the current text. Given that it at Level AAA, does 
it make sense to leave it in there?

UAWG moved around the levels of element-level customization and we 
believe that all of the items are included with the exception of Word 
spacing, which we had deliberately removed.

SH07) Word spacing seems to be missing all together. Is that an error or
conscious decision?

UAWG put word spacing back as a new bullet in 1.4.5 Word spacing, 
choosing from a range with at least 5 values
http://w3c.github.io/UAAG/UAAG20/#sc_145

*misc*

* Just an observation: There are a few aspects that are currently at a
higher level than I had suggested, including global line spacing,
justification, and margins. I assume y'all identified additional
rationale for them being at a higher level, which I am totally
comfortable with. :-)

SH08) * "Note: Any user settings from the platform for these characteristics
are implemented."
I cannot figure out what this means.

This note was added in response from requests from Microsoft.  UAWG 
removed the note and took the following actions:
a) removed the note from 1.4.1 and 1.3.1 because the notes are too broad
b) added a new success criterion "1.4.5: Default to platform text 
settings: The user can specify that platform text settings be used as 
the default values for text configuration. (Level AA)"
c) clarified 5.1.3 so that it only applies to implementing the 
accessibility guidelines of the platform and not to user settings
d) removed 1.4 note #1 because it was incorporated into the success 
criteria handles
e) moved 1.4 note to Conformance Applicability Notes

9) * "1.4.4 Configured and Reflowed Text Printing: The user can print 
the rendered content, and the following are all true: (Level AA) @@"
Just noting the "@@" there. :-)
[removed]

And some typos-type stuff I noticed:
* "The user can specifiy that multi-column text blocks be reflowed into
a single column (1.8.14, Level AA)"
specifiy -> specify
* "Summary: ... The user can specifiy that multi-column text blocks be
reflowed into a single column (1.8.14, Level AA)"
doesn't match below: "1.8.13 Multi-Column Text Reflow:" ... "1.8.14
Ignore Fixed Unit Dimensions:"
[fixed, thank you]
