Here is the test page for the 'YellowBlock' processor.

This processor puts the block contents into a fancy pale yellow box,
to higlight it.  Note that it processes the markup in the content.

== processor block ==
Here is the processor block:
{{{
{{{#!YellowBlock
content
 * a bullet
'''bold'''
}} }
}}}

== result output ==
Here is the result from the processor:

{{{#!YellowBlock
content
 * a bullet
'''bold'''
}}}

== expected result ==
The expected output should be:

{{HTML(<div style="background-color:#ffffe0; padding:5px; border-style: solid none solid none; border-width: 1px 1px 1px 1px;">)}}
content
 * a bullet
'''bold'''
{{HTML(</div)}}
