a 태그에서 title 속성 값에 줄바꿈..

[lacovnk]

a 태그에서 title 속성을 주면, 툴팁이 뜹니다.

이때, ""로 쌓인 값 중간에 줄바꿈(\n)이 있으면

IE는 툴팁이 세로로 확장되는 반면에, firefox는 특수문자로 깨져서 보이는군요;

원래 표준이 아닌 것인가요?;

6.2 SGML basic types

The document type definition specifies the syntax of HTML element content and attribute values using SGML tokens (e.g., PCDATA, CDATA, NAME, ID, etc.). See [ISO8879] for their full definitions. The following is a summary of key information:

    * CDATA is a sequence of characters from the document character set and may include character entities. User agents should interpret attribute values as follows:
          o Replace character entities with characters,
          o Ignore line feeds,
          o Replace each carriage return or tab with a single space.

HTML4.01문서를 보니,
title 애트리뷰트는 Text형식이고 Text형식은 CDATA 형식이고
CDATA에서는 LF는 무시하고 CR는 한개의 공백으로 처리한다고 되어 있네요...

쩝~~~Firefox는 좀 엄격하다는....
