border-top is a shorthand for <border-top-pattern> | ( <border-top-style> || <border-top-width> || <border-top-align> ).
border-right is a shorthand for <border-right-pattern> | ( <border-right-style> || <border-right-width> || <border-right-align> ).
border-bottom is a shorthand for <border-bottom-pattern> | ( <border-bottom-style> || <border-bottom-width> || <border-bottom-align> ).
border-left is a shorthand for <border-left-pattern> | ( <border-left-style> || <border-left-width> || <border-left-align> ).
-obfl-underline is a shorthand for <-obfl-underline-pattern> | ( <-obfl-underline-style> || <-obfl-underline-width> || <-obfl-underline-align> ).
A value "none" means that both x-pattern and x-style are set to none (similar to list-style).
border-style, border-width and border-align shorthands (for setting different values on the four sides) also exist, but no border-pattern shorthand.
When the value of "x-pattern" is "none" (or an invalid pattern), the "x-style", "x-width" and "x-align" properties are used to compute the border; otherwise, "x-style", "x-width" and "x-align" are ignored (similar to list-style-image and list-style-type).
Possibly "x-pattern" and "x-style" could be merged into a single property "x-style".
Possibly we can even skip the "x-pattern", "x-style", "x-width" and "x-align" properties altogether. "pattern", "style", "width" and "align" could still be mentioned in the definitions of "border", "border-top", etc., but as values, not as properties. "pattern" would be equivalent to "braille-character".
