RFC2253 section 3:
attributeValue = string,
string = *( stringchar / pair ) / ...
stringchar = <any character except one of special, "\" or QUOTATION>,
special includes "=".
Draft section 3:
; The following characters are to be escaped when they appear
; in the value to be encoded: ESC, one of <escaped>, leading
; SHARP or SPACE, trailing SPACE, and NULL.
string = ...
escaped = DQUOTE / PLUS / COMMA / SEMI / LANGLE / RANGLE
And the grammar:
attributeValue = string / ...
string = leadchar [*stringchar trailchar] and <pair>s / ...,
leadchar, stringchar, trailchar = LUTF1, TUTF1, SUTF1 and more,
LUTF1, TUTF1 and SUTF1 all include %3D ("=").
