Field sigils

The character in front of a name says which value is meant and how it is written into the page. None of these opens a level - the value is spliced in where the tag stood.

Form Writes
{$name} The field, through the sanitize chain
{!name} The same field raw - the sanitize chain is skipped
{?name} The field as a query fragment: &name=url+encoded
{^name} The field as JSON, escaped for a double-quoted HTML attribute; an array is encoded whole
{#name} An option or parameter of the tag
{&name} A property of the tag

Field: Tom & Jerry

JSON in an attribute

The JSON form is made for mount points of client-side components: JSON.parse(elem.getAttribute('data-props')) reads it back, with no custom tag and no {ignore} pipe.
