TAB-1273: Non-Alphabetical Tables and Lists

["Dr. Stanley Doherty" <stan@modularwriting.com>]

I did some lightweight analysis on the tables and lists in the DITA 1.3 Base spec that were:
* sorted alphabetically
* not sorted alphabetically
* "other" -- sorting not relevant
 
Patrick Durusau's feedback that the reading experience of the spec would be enhanced with a higher percentage of sorted tables and lists is correct. The information in the spec with greatest frequency of unsorted tables and lists were:
- DITA markup element tables
- Terminology lists
- Attribute lists
Targeting those lists for alphabetization in the next version of the spec would have a positive effect on readability. That is my recommendation. 

NOTE: Although all the table rows in the 182 Appendix C Content Models are sorted, very few of the comma-separated "contained in" lists are sorted. To some extent, that is a larger readability issue but was outside teh scope of the TAB-1273 feedback.
