This attribute is used in order to to make it safer for authors to embed untrusted resources where they expect a certain content type. The attribute specifies that the resource specified by the
data
attribute is only to be used if the value of the
type
attribute and the Content-Type of the aforementioned resource match.
The
typemustmatch
attribute must only be used when both the
type
and
data
is also being used.
The
typemustmatch
is a boolean attribute. If the attribute is present, its value must either be the empty string or a value that is an ASCII case-insensitive match for the attribute's canonical name, with no leading or trailing whitespace (i.e. either typemustmatch or typemustmatch="typemustmatch")..
typemustmatch | true/false | Specifies whether the type attribute and the actual content of the resource must match to be displayed |
