[!]Any Text to be Hidden[/!]
To hide comments in HTML pages so that you can see them when you're developing a template, but web visitors will not see them, put them inside a comment context. Anything inside the [!] context will be hidden, and WebDNA will not execute.
Example (normally you would put the following text into a .tpl file on your server and use a web browser to link to it):
Many times you will want to keep notes for yourself in a WebDNA template, yet
you do not want outsiders to see these notes. Unlike HTML comments, which are sent
to the browser even though they are hidden from view (and can be seen with a View
Source command), WebDNA comments never get sent to the remote browser. This shortens
download times, and provides some level of protection against prying eyes.
