/**
Highlighting tags are markers that denote a highlighting category.
They are [associated](#highlight.styleTags) with parts of a syntax
tree by a language mode, and then mapped to an actual CSS style by
a [highlighter](#highlight.Highlighter).

Because syntax tree node types and highlight styles have to be
able to talk the same language, CodeMirror uses a mostly _closed_
[vocabulary](#highlight.tags) of syntax tags (as opposed to
traditional open string-based systems, which make it hard for
highlighting themes to cover all the tokens produced by the
various languages).

It _is_ possible to [define](#highlight.Tag^define) your own
highlighting tags for system-internal use (where you control both
the language package and the highlighter), but such tags will not
be picked up by regular highlighters (though you can derive them
from standard tags to allow highlighters to fall back to those).

/**
This function is used to add a set of tags to a language syntax
via [`NodeSet.extend`](#common.NodeSet.extend) or
[`LRParser.configure`](#lr.LRParser.configure).

The argument object maps node selectors to [highlighting
tags](#highlight.Tag) or arrays of tags.

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.

In this notation, node names that contain `/`, `!`, `*`, or `...`
must be quoted as JSON strings.

For example:

```javascript
parser.withProps(
  styleTags({
    // Style Number and BigNumber nodes
    "Number BigNumber": tags.number,
    // Style Escape nodes whose parent is String
    "String/Escape": tags.escape,
    // Style anything inside Attributes nodes
    "Attributes!": tags.meta,
    // Add a style to all content inside Italic nodes
    "Italic/...": tags.emphasis,
    // Style InvalidString nodes as both `string` and `invalid`
    "InvalidString": [tags.string, tags.invalid],
    // Style the node named "/" as punctuation
    '"/"': tags.punctuation
  })
)
```
