This tag is used to write or read any options to TML tags. The value of the option is in the content of this tag. In practise this tag is mostly used in <tml:element> and <tml:include>, where it passes options to the WebTML element to execute or the TML-Module to embed.
The tag knows two modi "get" and "set" that either put out the value of an option or set the value of it. The mode can be chosen directly by attribute "mode" or implicitly by the existence of content in the option tag. In the latter case the "set" mode is only used when content is present.
