Summary of Issue: SC4.1.1  Sufficient Techniques
Comment (Including rationale for any proposed change):
Sufficient Techniques for SC 4.1.1 are listed as below:
1. G134: Validating Web pages
2. G192: Fully conforming to specifications
3. H88: Using HTML according to spec
4. Ensuring that Web pages can be parsed by using one of the following techniques:
 *H74: Ensuring that opening and closing tags are used according to specification (HTML)
 *H75: Ensuring that Web pages are well-formed (HTML) 

For HTML, it means that using only H74 would be sufficient for meeting this Success Criterion. 

However, authors won't be able to ensure that "elements are nested according to their specifications, elements do not contain duplicate attributes, and any IDs are unique" by using H74.

One more issue. Does H75(well-formed HTML) also mean that "elements do not contain duplicate attributes, and any IDs are unique"? In general, "well-formed" would imply that "elements have complete start and end tags, elements are nested according to their specifications". If it also means "not duplicated attributes" and "properly nested elements", please make sure that this is specified in the Understanding and H75 Technique document. 

"well-formed" is understood differently among web developers. Need to clarify what it exactly means.

Proposed Change:
1. G134: Validating Web pages
2. G192: Fully conforming to specifications
3. H88: Using HTML according to spec
4. H74: Ensuring that opening and closing tags are used according to specification (HTML) AND H00: Ensuring that elements are nested according to their specifications (HTML) AND H000: Ensuring that elements do not contain duplicate attributes (HTML) AND H000: Ensuring that any IDs are unique (HTML)
5. H75: Ensuring that Web pages are well-formed (HTML) AND H000: Ensuring that elements do not contain duplicate attributes (HTML) AND H000: Ensuring that any IDs are unique (HTML)
