+Element submanifest

+One or more submanifest elements may be specified. Each element describes a
+single manifest to be checked out as a child.
+.PP
+Attribute `name`: A unique name (within the current (sub)manifest) for this
+submanifest. It acts as a default for `revision` below. The same name can be
+used for submanifests with different parent (sub)manifests.
+.PP
+Attribute `remote`: Name of a previously defined remote element. If not supplied
+the remote given by the default element is used.
+.PP
+Attribute `project`: The manifest project name. The project's name is appended
+onto its remote's fetch URL to generate the actual URL to configure the Git
+remote with. The URL gets formed as:
+.IP
+${remote_fetch}/${project_name}.git
+.PP
+where ${remote_fetch} is the remote's fetch attribute and ${project_name} is the
+project's name attribute. The suffix ".git" is always appended as repo assumes
+the upstream is a forest of bare Git repositories. If the project has a parent
+element, its name will be prefixed by the parent's.
+.PP
+The project name must match the name Gerrit knows, if Gerrit is being used for
+code reviews.
+.PP
+`project` must not be empty, and may not be an absolute path or use "." or ".."
+path components. It is always interpreted relative to the remote's fetch
+settings, so if a different base path is needed, declare a different remote with

+If not supplied the remote and project for this manifest will be used: `remote`
+cannot be supplied.
+.PP
+Projects from a submanifest and its submanifests are added to the
+submanifest::path:<path_prefix> group.
+.PP
+Attribute `manifest\-name`: The manifest filename in the manifest project. If not
+supplied, `default.xml` is used.
+.PP
+Attribute `revision`: Name of a Git branch (e.g. "main" or "refs/heads/main"),
+tag (e.g. "refs/tags/stable"), or a commit hash. If not supplied, `name` is
+used.
+.PP
+Attribute `path`: An optional path relative to the top directory of the repo
+client where the submanifest repo client top directory should be placed. If not
+supplied, `revision` is used.
+.PP
+`path` may not be an absolute path or use "." or ".." path components.

+Attribute `groups`: List of additional groups to which all projects in the
