// "display_text" : "Terms of Service",

// } ]
// }
//
// Caveats:
// 1. '{' and '}' may be displayed by escaping them with an apostrophe in the
// template string, e.g. template "Here is a literal '{'".
// 2. Two or more consecutive dollar signs in the template string will not
// expand correctly.
// 3. "${" anywhere in the template string is invalid.
// 4. "\n" embedded anywhere in the template string, or an empty template
// string, can be used to separate paragraphs.
// 5. Because a single apostrophe before a curly brace starts quoted literal
// text in MessageFormat, "'{0}" gets treated as a literal. To avoid
// situations like these, setting |escape_apostrophes| to true will escape
// all ASCII apostrophes by doubling them up.
