The following elements and attribute are currently in the Tite schema but not mentioned in the Tite prose documentation. According to Perry Trolard, they should be removed. He said this course of action was broadly affirmed in February 2010 by Dan, Laurent, and Lou.
A. <biblScope>: Removing reduces complexity of schema. Need to be realistic about what's possible to do reliably at vendor
B. <measureGrp>: Mistakenly included in Tite.
II. ATTRIBUTE OR ATTRIBUTE CLASS: NOTES ON REMOVAL
A. @decls: Its purpose is to coordinate with the header, but Tite has no header.
B. att.naming: It's too much to expect keyboarders to refer to canonical names or to discern roles, so remove:
1. @key and @ref from <author>, <docAuthor>, <docTitle>, <resp>, and <title>
2. @key, @ref, @nymRef from <name>
3. @key, @ref, @nymRef, @role from <pubPlace>
C. There's a desire to limit the ways to express quantities in dates, times, spans of text, and numbers by removing all EXCEPT:
1. @when, @from, and @to from <date> (that is, removing @period, @notBefore, @notAfter, @atLeast, @atMost, @source, @type, @calenar, @cert, @extent, @max, @min, @precision, @quantity, @resp, @scope, and @unit)
2. @when and @type from <time> (that is, removing @period, @notBefore, @notAfter, @from, @to, @atLeast, @atMost, @max, @min, @precision, @quantity, @extent, @scope, and @unit)
3. @extent and @reason from <gap> and <unclear> (that is, removing @atLeast, @atMost, @source, @max, @min, @quantity, @unit, @precision, and @scope)
4. @type from <num> (that is, removing @atLeast, @atMost, @min, @max, and @value)
D. @ed should be removed from <cb>, <cols>, <milestone>, and <pb>: Vendor won't know about differences between editions.
E. @ref: When adding <g> before the release of 1.0, it was decided that it would be used without reference to a <glyph> and without attributes, so it's unneeded.
F. Other attributes to be removed to reduce encoding complexity or because their use would be inappropriate for a keyboarder at a vendor:
1. @type from <abbr>, <ab>, <cite>, <pb>, <q>, and <stage>
2. @role from <cell>
3. @version from <desc>
4. @place from <figure>
5. @notation from <formula>
6. @part from <ab> and <l>
7. @who from <q>
8. @width, @height, and @scale on <graphic>
9. @cert, @resp, @anchored, and @targetEnd from <note>
10. @evaluate and @cRef from <ptr> and <ref>
