I'm aware of this issue, but I don't know any good way to solve it. It's a more general XML issue really.

LSP does only know XML, not XHTML, and the © entity is defined in XHTML.

A workaround is to include the XHTML entity declaration DTD in the LSP file, something like this:

%lat1;
%special;
%symbol;
]>
