Reflecting Element References

[cyns]

WICG/AOM has reached a consensus on a proposal to reflect ARIA element references. Is this proposal acceptable to the ARIA WG?

• supports element references (e.g. aria-activedescendant) and arrays of element references (e.g. aria-describedby)
• uses a "frozen array" implementation and does not wait for Observable Arrays to be implemented
• does not "sprout" attributes when IDL values are set. Simple ARIA values would continue to sprout attributes

Original AOM explainer text:
https://github.com/WICG/aom/blob/gh-pages/aria-reflection-explainer.md#reflecting-element-references

PR to remove sprouting for element references:
WICG/aom#181 (fixed link)

Work Items:

• Add these attributes to ARIA Mixin IDL
• Add example to ARIA 6.3 Enumerated Attribute Values
• Create test cases

Link to the PR seems wrong. WICG/aom#181, right?
