+        @param pBegin  The range (that must be valid) from non-null pBegin,
+        inclusive. to non-null pEnd, exclusive, forms the body of the
+        Content-Type header field.  It must be of the form
+
+          token "/" token *(";" token "=" (token / quoted-string))
+
+        with intervening linear white space and comments (cf. RFCs 822, 2045).
+        The RFC 2231 extension are supported.  The encoding of rMediaType
+        should be US-ASCII, but any Unicode values in the range U+0080..U+FFFF
+        are interpretet 'as appropriate.'
+
+        @param pType  If not null, returns the type (the first of the above
+        tokens), in US-ASCII encoding and converted to lower case.
+
+        @param pSubType  If not null, returns the sub-type (the second of the
+        above tokens), in US-ASCII encoding and converted to lower case.
+
+        @param pParameters  If not null, returns the parameters as a list of
+        INetContentTypeParameters (the attributes are in US-ASCII encoding and
+        converted to lower case, the values are in Unicode encoding).  If
+        null, only the syntax of the parameters is checked, but they are not
+        returned.
+
+        @return  Null if the syntax of the field body is incorrect (i.e., does
+        not start with type and sub-type tokens).  Otherwise, a pointer past the
+        longest valid input prefix.  If null is returned, none of the output
+        parameters will be modified.
