ISSUE-609: Text Alt Comp section does not explicitly disallow empty strings as a valid label

empty string labels are technically valid

Text Alt Comp section does not explicitly disallow empty strings as a valid label

State:
CLOSED
Product:
ARIA 1.1 Name Computation
Raised by:

Description:
Text Alt Comp section does not explicitly disallow empty strings or whitespace-only strings as a valid label.

2.D. currently states, "The last resort is to use text from a tooltip attribute (such as the title attribute in HTML). This is used only if nothing else, including subtree content, has provided results."

Should be updated to be something more explicit like:
"If all previous steps, including subtree content, have provided only null, empty, or whitespace-only strings, the last resort is to use the text value of the host language's tooltip attribute, such as the title attribute in HTML."

We think that the text is fine and rendering tooltips in browsers from the title attribute is not defined as normative behavior even though it is implemented in many browsers.
