6.1.3 EnclosingTag Objects

content
An instance of the Content class which is created during the constructor.

has_content( )
Returns 1 to inform the template parser that the tag encloses content.

append( item)
Called by the template parser to append the content in the item argument to the tag. The method implementation simply passes item to the append() method of the content member.

You should override this method if you need to maintain multiple content lists within your tag.

to_html( ctx)
The template interpreter calls this method to convert the tag to HTML for the execution context in the ctx argument. The default implementation passes ctx to the the to_html() method of the content member.

You must override this method in your tag class to perform all actions which are necessary to ``execute'' the tag.
