Consider 1 item arrays for PipeDelimited and SpaceDelimited as conflicting #13

Right now the assumption is made that two parameters can be identified by differing styles, thus spaceDelimited and pipeDelimited cannot conflict.

That makes sense mostly:

spaceDelimited: blue%20black%20brown
pipeDelimited: blue|black|brown

But what if they can have one element? Nothing gets delimited.

spaceDelimited: blue
pipeDelimited: blue

In that instance, nothing differs between styles and there is no parameter name to identify them.

Solution:

if both parameters meet the following criteria, then they conflict:

• schema->canBe(array)
• style:spaceDelimited or style:pipeDelimited
• schema does not specify minItems: 2 (or more)
  • this point can only be achieved once the reader looks into minItems
  • this point can only be achieved once the reader looks into minProperties
