Functions are composed of HTML and Vortex statements. Any text or tag which is not recognized as a Vortex statement, directive, variable, comment or function call is simply printed out. For example, the HEAD and TITLE tags in the banner function above are not Vortex statements, so they are printed.

To aid in code formatting, any leading whitespace on a literal line of HTML is stripped in the output. This allows proper indentation of source code in the Vortex script, while reducing redundant space in the output. In fact it can lead to a significant reduction in the size of the output, increasing response time for users on slow connections. (This stripping does not happen within VERB elements; see here.)
