  • Attribute status is marked by: §d=distinguished, §v=value, or §m︎=metadata.
  • Attribute value constraints are marked with ⟨…⟩ (for DTD constraints) and ⟪…⟫ (for augmented constraints, added in v35.0).
  • Changes in status or constraints are shown with ➠, with identical sections shown with ….
  • Newly ordered elements are indicated with ⇣; newly unordered with ⇟.
  • Newly tech-preview items are marked with 🅟; newly graduated from tech preview with ⓟ.
