Message
element
should not contain HTML
Explanation
This value appears to contain HTML markup. Be advised that clients will behave unpredictably in the presence of such markup: some will interpret it as HTML, others will strip it, and still others will display the markup itself.
Solution
Consider removing the markup.
If the purpose of the markup is to escape the use of an HTML entity, use this table to find the Entity Number to replace the escaped version of the Entity Name. For example:
©
becomes:
©
Encoding of the characters "&"
and "<"
are especially problematic in places like RSS 2.0 titles. For the widest
interop, the
RSS Profile
recommends the use of the hexadecimal character reference
"&
" to represent "&
" and
"<
" to represent "<
".
