future to support additional kinds of parent resources such as one
of the route kinds. \n It is invalid to reference an identical parent
more than once. It is valid to reference multiple distinct sections
within the same parent resource, such as 2 Listeners within a Gateway.
\n It is possible to separately reference multiple distinct objects
that may be collapsed by an implementation. For example, some implementations
may choose to merge compatible Gateway Listeners together. If that
is the case, the list of routes attached to those resources should
also be merged. \n Note that for ParentRefs that cross namespace
boundaries, there are specific rules. Cross-namespace references
are only valid if they are explicitly allowed by something in the

the Route. \n Note that there are specific rules for ParentRefs
which cross namespace boundaries. Cross-namespace references
are only valid if they are explicitly allowed by something
in the namespace they are referring to. For example: Gateway
has the AllowedRoutes field, and ReferenceGrant provides
a generic way to enable any other kind of cross-namespace
reference. \n Support: Core"

port:
description: "Port is the network port this Route targets.
It can be interpreted differently based on the type of
parent resource. \n When the parent resource is a Gateway,
this targets all listeners listening on the specified
port that also support this kind of Route(and select this
Route). It's not recommended to set `Port` unless the
networking behaviors specified in a Route must apply to
a specific port as opposed to a listener(s) whose port(s)
may be changed. When both Port and SectionName are specified,
the name and port of the selected listener must match
both specified values. \n Implementations MAY choose to
support other parent resources. Implementations supporting
other types of parent resources MUST clearly document
how/if Port is interpreted. \n For the purpose of status,
an attachment is considered successful as long as the
parent resource accepts it partially. For example, Gateway
listeners can restrict which Routes can attach to them
by Route kind, namespace, or hostname. If 1 of 2 Gateway
listeners accept attachment from the referencing Route,
the Route MUST be considered successfully attached. If
no Gateway listeners accept attachment from this Route,
the Route MUST be considered detached from the Gateway.

sectionName:
description: "SectionName is the name of a section within
the target resource. In the following resources, SectionName
is interpreted as the following: \n * Gateway: Listener
Name. When both Port (experimental) and SectionName are
specified, the name and port of the selected listener
must match both specified values. \n Implementations MAY
choose to support attaching Routes to other resources.
If that is the case, they MUST clearly document how SectionName
is interpreted. \n When unspecified (empty string), this
will reference the entire resource. For the purpose of
status, an attachment is considered successful if at least
one section in the parent resource accepts it. For example,
Gateway listeners can restrict which Routes can attach
to them by Route kind, namespace, or hostname. If 1 of
2 Gateway listeners accept attachment from the referencing
Route, the Route MUST be considered successfully attached.
If no Gateway listeners accept attachment from this Route,
the Route MUST be considered detached from the Gateway.
