Where the path comes from

Option	Meaning
`Parents`	The relations from a node to its parent, in priority order. Empty means flat.
`Domains`	`UrlDomain { Host, RootId }`: each host serves the tree below its root node, and the root is `/`.
`FallbackRootId`	The root for unknown hosts: localhost, staging, tests. Default: the first domain's root.
`OwnHosts`	More hosts the site runs at, separated by commas: `"staging.site.com, localhost"` (§18.2).
`Scheme`	Scheme of absolute URLs. Default `https`.
`MaxDepth`	Limit on the walk up the parents, against cycles. Default 32.

A UrlParentRelation names its relation by ParentRelationName (CodeName or full name) or ParentRelationId; ParentIsRelationSource (default true) puts the parent on the source side. With several Parents, the manager follows the first that accepts the node's type and has a parent for it. So pages can hang under pages through one relation and documents under pages through another, and one URL crosses both. Domains are not stored on nodes, so the same content runs unchanged on localhost.

└─ mobile

Both leaves have the address info. An address only has to be unique among nodes that would otherwise get the same URL.
