If you return HRESULT rather than BOOL you don't need the hack in the
caller.  Generally, many of the helper functions in this series would
be better returning HRESULT.

static const char xml_header[] = "...";

You can then use sizeof() instead of strlen below.

This is unused at the moment, add it in a later patch when needed.

Zeroing the string is expensive just to get a trailing \0.

You'd return E_OUTOFMEMORY here.

I'll let you off immediately free()ing the string you've allocated,
since otherwise doing this later in one patch would make that patch
larger.

So here you'd just return write_and_send_message();
