consider unresolved documents (the document() function) non-lethal.
suppress the whitespace stripping (on data files only).

another as yet unresolved discrepancy is that in perl 5.005_02 the pattern /^(a)?(?(1)a_bar_b)+$/ matches the string "a", whereas in pcre it does not. however, in both perl and pcre /^(a)?a/ matched against "a" leaves $1 unset.
this applies whether or not the follow - ing character would otherwise be interpreted as a meta - character, so it is always safe to precede a non-alphanumeric with "\" to specify that it stands for itself.
