To let the user specify the display characteristics of a block of unknown HTML in FrontPage, we have three attributes on the WEBBOT pseudo-tag. They are only valid when the StartSpan attribute is also specified (can’t use with EndSpan.) Also, when using Designer HTML, the BOT attribute is always set to “HTMLMarkup”. The new attributes are:
U-SRC=filenamePoints to an image file to use to display the unknown HTML block in FrontPage. If the image is a file: URL on the local machine then it will be automatically included into the web and the URL adjusted to point to the version contained in the web.
Only image files are allowed for the U-SRC tag. Included HTML is not allowed. If text is needed for display then it should either be encoded into the image or the ALT attribute should be used instead of the U-SRC attribute.
ALT=textLimited HTML text to show inside a rectangle in FrontPage as the display for the unknown HTML block. If both U-SRC and ALT are specified, then U-SRC is used in preference to ALT. Typically, however, only one or the other would be specified. The set of allowed HTML tags in the ALT attribute is detailed below.
TAG=textAn optional attribute that specifies the tag level that the ALT attribute should be entered as. You can specify any block-like HTML tag name (without < > brackets) that is beneath the BODY tag. For instance, to have the HTML entered into the document at the level of a <p> paragraph tag, use TAG=p. Or to make it a heading, use TAG=h1. If omitted, it is inserted as a text/character-level tag.
Here is an example:
<!--WEBBOT bot="HTMLMarkup" ALT= "<Font Size=+3><I>Foobar ISV Feature Placeholder</I></FONT>" StartSpan -->
[## amazingly ugly ISV syntax that either a server pre-processor knows, or that a new version of some web browser knows, but FrontPage doesn’t ##]
<!--WEBBOT bot="HTMLMarkup" EndSpan -->
In this case the ALT attribute is specified for a simple textual display of the unknown HTML.
