changes for help

Hi folks,In response to the comments to the help success criteria  ( https://github.com/w3c/wcag21/issues/32) we have come out with the following changed wording. Please compare to the original (see bellow) and see if you are OK with the changes....


new wording:




Comprehension support is available via one or more of the following: 

For numerical content: Charts, tables, graphics or non-numerical text content are available that summarize numerical information;
For forms:  non-standard controls have instructions, and  multi-step forms provide information about a user's position in the form.
 Long  blocks of text:  are divide  with heading, keywords are visually emphasized or a summary is provided  
For directions: Alternative terms are available for  relative and cardinal directions.

 There are exceptions where: 
  the content will be penalized for not conforming to a given style (such as a dissertation or a Ph.D. proposal); 
 a different structure is an essential part of the main function of the site (for example, a game or a reading test); 
 if the style is an essential part of the main function of the site, such as a literary work;
 for numerical information where the target audience is in a profession that requires a knowledge of maths.
  
  definitions:
 - Keywords: Author defined terms that identify the purpose of the passage. (Note the understand section will describe this process of identifying keyword)
 - Non-Standard controls: Scripted  interactive elements which do not behave like a named control in the host language.
 - Long blocks of content are sections of text that are not divided  by a header, list, or named region and are 300 words or more (or xx characters in Chinese and Japanese) .
     To help you compare here is the old version:
Comprehension support is available via: 
 
 Charts, tables, or graphics to summarize complex numerical information;
  Summaries of long documents;
  Emphasis of key words in long documents;
  Instructions for non-standard controls;
  Information about a user's position in multi-step forms;
  Alternative terms for relative and cardinal directions;
  Non-numerical versions of numerical values.






 
 
 

All the best
