because there are four options to consider, a CASE object seems like the
perfect solution to me. Let's try:

8<--

80 = CASE
80 {
  key.cObject = COA
  key.cObject {
# set the author flag
    10 = TEXT
    10.value = a
    10.fieldRequired = author
# set the email flag
    20 = TEXT
    20.value = e
    20.fieldRequired = author_email
  }
# default: do nothing
#  default = NOOP
# only author
  a = TEXT
  a.field = author
  e = TEXT
  e.field = author_email
  ae = TEXT
  ae.dataWrap = {field:author} ({field:author_email})
  stdWrap {
    required = 1
    wrap = <meta name="author" content=" | " />
  }
}

-->8

I first thought about using a bitmap as key value, but "a" and "e" IMHO
provide more information to the reader. So in the end this version is
not really simpler, but at least more readable.

Best regards
Thorsten
