Because MARC tags can according to ISO2709 have alphanumeric values -
whilst it isn't ambiguous what
It could be confusing!
Also for indicators you may want to form a query of the form
marc.245$a = "Smith" where the Indicator1 = 4
Which isn't the same as
marc.245$a = "Smith" and marc.245i1 = 4 (as this does not imply that the
second operand applies to the same marc field as the first).
Hence for indicators is seems likely that these would have to be handled
by relational modifiers.
