:mrdocs:

Add an attribute of the specified `name` and specified `value` to the currently open element. `value` can be of the following types: `char`, `short`, `int`, `bsls::Types::Int64`, `float`, `double`, `bsl::string`, `bdlt::Datetime`, `bdlt::Date`, and `bdlt::Time`. Precede this name="value" pair with a single space. Wrap line (write the attribute on next line with proper indentation), if the length of name="value" is too long. Optionally specify a `formattingMode` used to control the formatting of the `value`. If `value` is of type `bsl::string` or convertible to `bsl::string_view`, the presence of invalid input stops the transfer of data to the output specified on construction (see {Valid Strings}). If `value` is of type `bsl::string` or convertible to `bsl::string_view`, any special characters in `value` are escaped (see {Special Characters}). If `value` is of type `char`, it is cast to a signed byte value with a range `[ ‐128 .. 127 ]`. The behavior is undefined unless the last manipulator was `openElement` or `addAttribute`.
