# Changes

# Requirements satisfied
N/A (no requirement document)

# Dependencies met (or not)
Met.
All normative dependencies fall into one of:
* stable (>=CR) W3C specs:
    - CSS-CASCADE-4 (CR)
    - CSS-DISPLAY-3 (CR)
    - CSS-MASKING-1 (CR)
    - CSS-VALUES-3 (CR)
    - CSS2 (REC)
    - CSS3-BREAK (CR)
    - CSS3-IMAGES (CR)
    - CSS3-TEXT-DECOR (CR)
    - CSS3BG (CR)
    - SVG11 (REC)
* Stable non-W3C specs:
    - HTML (LS)
    - RFC2119
    - RFC6919
    - UAX11
    - UAX24
    - UAX50
    - UAX9
    - Unicode

* Newer specs used for more up to date versions of definitions and terminology covering concepts that preexist in older more mature specs:
    - CSS-BOX-3 (WD) for properties that exist in CSS2 (REC):
    - CSS-INLINE-3 (WD) for properties and modern vocabulary describing inline text layout mechanisms that exists in CSS2 (REC):
    - CSS-OVERFLOW-3 (WD) for new terminology to discuss parts of scrollable elements, which exists in CSS2 (REC)
    - CSS-SIZING-3] (WD) for new terminology to discuss sizing mechanisms that exist since CSS2 (REC)
    - CSS3PAGE (WD) for the term "page progression direction", which refers to a concept that preexists in CSS2 (REC)

* Other reasons
    - CSS-RUBY-1 (WD), to specify types of boxes that writing-modes **do not** apply to
   - CSS-WRITING-MODES-4 (CR) mentioned only in the change section and notes for at-risk features that were dropped from Level 3
    - CSS3COL (WD) referred to only to say that the behavior is undefined
