We currently say:

"Applications claiming to implement "Traditional Complex Number Notation" shall allow traditional inline notation for complex numbers, that is, "i" or "j" optionally prefixed with Number produces a type Complex."

That's incorrect. A complex type consists of a real number plus an imaginary number.

Rather than filing a separate JIRA issue, why do we define acceptance of complex types by infix operators here? Isn't this covered by Number as a type already?

What does the "...no required to accept the Text type as equivalent." mean?

Most of this looks like repetition so I am deleting it until the case is made for its return.
