message.subject.source  = "static"

Or, to set one or more headers:

0.message.header.name    = "content-type"
0.message.header.value   = "application/xml"
0.message.header.source  = "static"

1.message.header.name    = "content-encoding"
1.message.header.value   = "identity"
1.message.header.source  = "static"

2.message.header.name    = "accept-encoding"
2.message.header.value   = "identity"
2.message.header.source  = "static"

3.message.header.name    = "id"
3.message.header.value   = "//menu/id/text()"
3.message.header.source  = "jpath"
3.message.header.required = true
