 * #### Notes
 *
 * An `en` string is required, as the default fallback, and it should usually
 * contain a string in US English. _(That's the macOS default,
 * as a Brit this of course pains me! -Nick)_
 *
 * The predefined languages in this interface definition are the ones that
 * PopClip currently ships with translations for.
 * But you can include other languages too.
 * For example you can include `en-GB` or `en-CA` string to have different
 * regional spellings.

/**
 * A string with a special format to declare an icon. Used for {@link Extension.icon} and {@link Action.icon}.
 *
 * Icons may be specified in a few different ways:
 *
 * * **Image file:** A string with suffix `.png` or `.svg` matching the name of an image file in the extension package. Images must be in either PNG or SVG format.
 * The icons should be square and monochrome, black, on a transparent background. You can use opacity to create shading.
 * PNG icons should be at least 256x256 pixels in size.
 *
 * * **SF Symbol:** A string of the form `symbol:<symbol name>` specifies an [SF Symbols](https://sfsymbols.com) name, for example `symbol:flame`.
 * Symbols are available starting on macOS 11.0 and above, but some symbols require higher macOS versions, as indicated in the
 * "Availability" panel in Apple's SF Symbols browser app.
 *
 * * **Text icon:** A string of the form `text:<text icon specifier>` instructs PopClip to generate a text-based icon, as described below.
 *
 * ### Text icons
 *
 * Text-based icons can up to three characters, on their own or within an enclosing shape. The enclosing shape is specified using different kinds of brackets around the text. The easiest way to explain is probably by example:
 *
 * * `text:A` - the letter A on its own
 *
 * * `text:(1)` - the digit 1 in an outline circle
 *
 * * `text:((本))` - the character 本 in a filled circle
 *
 * * `text:[xyz]` - the characters xyz in an outline square
 *
 * * `text:[[!]]` - the character ! in a filled square
 *

  * |`paste`|The app's Paste command must be available.|
  * |`formatting`|The selected text control must support formatting. (PopClip makes its best guess about this, erring on the side of a false positive.)|
  * |`weburl`|The text must contain exactly one web URL (http or https).|
  * |`weburls`|The text must contain one or more web URLs (http or https).|
  * |`email`|The text must contain exactly one email address.|
  * |`emails`|The text must contain one or email addresses.|
  * |`path`|The text must be a local file path, and it must exist on the local file system.|
  * |`option-foo=bar`|The current value of the option named `foo` must be equal to the string `bar`. (Boolean values match against strings `0` and `1`.)|
  *
  * A requirement can also be **negated** by prefixing `!`, to specify that the requirement must _not_ be met.
