Markup
Another type of placeholder is a markup placeholder. A markup placeholder can be "open", "close", or "standalone". This example shows open and close markup placeholders.
Click {#link}here{/link}. {#b}{$count}{/b}
{#link}
is an opening markup placeholder, while {/link}
is a closing markup placeholder.
Markup is not specific to any particular markup language such as HTML. The message formatter doesn't interpret markup. It simply passes pieces of markup through into the formatted result.
