of MAXUINT), TYPE is the nickname of the attribute value type, e.g.
_weight_ or _stretch_, and the value is serialized according to its type:
- enum values as nick or numeric value
- boolean values as _true_ or _false_
- integers and floats as numbers
- strings as string, optionally quoted
- font features as quoted string
- PangoLanguage as string
- PangoFontDescription as serialized by [method@Pango.FontDescription.to_string], quoted
- PangoColor as serialized by [method@Pango.Color.to_string]
Examples:
```
0 10 foreground red, 5 15 weight bold, 0 200 font-desc "Sans 10"
```
```
0 -1 weight 700
0 100 family Times
```
To parse the returned value, use [func@Pango.AttrList.from_string].
Note that shape attributes can not be serialized.</doc>
