[webkit-dev] how about nav-up, nav-right, nav-down, nav-left in CSS3-ui ?

[Ra Kyounga]

Hi, CSS developers, 

1]I need correct the wrong information of previous email 
https://bugs.webkit.org/show_bug.cgi?id=66027

2] Opera support these properties.

3]
And, I need your help. 
I think I have to modify cssgrammar.y
I'm not familiar with lex&yacc syntanx.

Let me explain it. 
According to the standard, the syntax is "nav-up:#<id attribute value>"
I just added new property name to CSSPropertyNames.in and checked if it works using CSSParser::parseValue(). 

It doesn't work as I expected.
Expected : string type, string value. 
Real : HexColor type(for example nav-up:#b1) or not parsed(nave-up:#foo)

In my guess, the css parser assumes that a css value (which starts with "#" ) should be a color value.
What should I do for my expected result?

Thank you in advance.
kyounga.
