sqAttribute constant
Escaping mode for text going into single-quoted HTML attribute values.
The result should not be used as the content of an unquoted or double-quoted attribute value.
Escapes single quotes (') but not double quotes ("),
and escapes < and > characters because they are not allowed
in strict XHTML attributes.
Implementation
static const HtmlEscapeMode sqAttribute = HtmlEscapeMode._(
'attribute',
true,
false,
true,
false,
);
