Re: No port attribute allowed on p:with-input of p:if?

Hi Martin,

You are right. The spec needs to explicitly state that a p:with-input on 
p:if is always anonymous, that is, no port may be specified in it.

The spec needs to a) explicitly define what it means by “anonymous input 
port“, it needs to b) say that p:with-input must not have a port 
attribute when used in p:viewport, p:for-each, p:choose, p:when, or p:if.
Thirdly unless the list was updated when fixing b), the spec needs to 
add p:if to the list in the bullet point “In a p:choose or p:when, it is 
a binding for the context item for the test expression(s).” of 
https://spec.xproc.org/master/head/xproc/#p.with-input

I’m going to file an issue at https://github.com/xproc/3.0-specification

And yes, in Erik’s book it should read “do not use a port attribute” 
(sloppy proofreading on my part, too…).
