The term "parsed unambiguously" is difficult to understand.
Change 4.1.1 to ""The structure of and relationships within web units and authored components can be determined without the need for user agents or assistive technologies to perform error correction.""
Eliminate the term ""parsed unambiguously"".
To make this requirement easier to understand, we have reworded SC 4.1.1 to clarify that it must be possible to parse content without the need for user agent repair. The revised SC reads as follows:
4.1.1 Content implemented using markup languages has elements with complete start and end tags, except as allowed by their specifications, and are nested according to their specifications. (Level A)
Note: Start and end tags that are missing a critical character in their formation, such as a closing angle bracket or a mismatched attribute value quote are not complete.
