9c20b91996-11-20Per Hedbor // The purpose of this module is to allow comments in the SPML source // that are invisible to average viewers, but can be seen with the // right magic incantation. Fnord! The special text is rendered in // the "sample" font, if available, which makes it possible for // someone looking at the mixed output to distinguish text that is for // public consumption from that which is restricted.

9c20b91996-11-20Per Hedbor // If you have a section of text (with markup, if desired) that you // may be planning on adding later, but don't want to generally // activate (the pointers may not have all been done, yet) you can use // this. It has other uses, too.

9c20b91996-11-20Per Hedbor // This is not a secure way to hide text, I would like to see a // version that requires authentication to turn on the "hidden" text, // but this simple version does not do that.

9c20b91996-11-20Per Hedbor // To use this in your SPML, enter the "hidden" text between a <FNORD> // and </FNORD>, you can include any additional markup you desire. // You may want to have a <P> or two to set it off, or use // <BLOCKQUOTE> inside. Here's a simple example:

9c20b91996-11-20Per Hedbor // The text that everyone sees. <FNORD>With some they // don't.</FNORD> And then some they do.

9c20b91996-11-20Per Hedbor // Since the excised text may be part of a sentence flow, its removal // may disrupt the readability. In this case an ALT attribute can be // used on the FNORD to give text for the mundanes to see. This text // should not have markup (some kinds might work, but others might // not). Here's an example of how that might be used:
3272521999-12-14Martin Nilsson 
9c20b91996-11-20Per Hedbor // This server <FNORD ALT="provides">will provide, when we // actually get to it,</FNORD> complete source for the ...

9c20b91996-11-20Per Hedbor // The way the normally hidden text is made visible is by including // "fnord" in the prestates (i.e. add "/(fnord)" before the "filename" // part of the URL). // Michael A. Patton <map@bbn.com>
