/// Node selectors may hold one or more (space-separated) node paths.
/// Such a path can be a [node name](#common.NodeType.name), or
/// multiple node names (or `*` wildcards) separated by slash
/// characters, as in `"Block/Declaration/VariableName"`. Such a path
/// matches the final node but only if its direct parent nodes are the
/// other nodes mentioned. A `*` in such a path matches any parent,
/// but only a single level—wildcards that match multiple parents
/// aren't supported, both for efficiency reasons and because Lezer
/// trees make it rather hard to reason about what they would match.)
///
/// A path can be ended with `/...` to indicate that the tag assigned
/// to the node should also apply to all child nodes, even if they
/// match their own style (by default, only the innermost style is
/// used).
///
/// When a path ends in `!`, as in `Attribute!`, no further matching
/// happens for the node's child nodes, and the entire node gets the
/// given style.
