Arguably the most important LXP tag is the <lxp> tag itself, which enables an
LXP region
. This is similar to a <script> tag, or the PHP short tag, in that it instructs the
LXP module to begin looking for LXP content.
Unlike PHP, however, while parsing an LXP region the module will simply ignore any tags that it does not recognize as
an LXP tag. The <lxp> tag simply enables the ability to use LXP tags in a given
region without impairing your ability to write normal HTML mark-up (though the effect of LXP tags can control which parts
of the HTML are displayed).
It should follow from this discussion that </lxp> closes an LXP region and
disables the ability to use LXP tags until the next <lxp> tag is opened.
Note: An LXP document does not automatically look for LXP tags. A document will be rendered faster if LXP regions are
limited to areas requiring LXP capabilities, as it is more involved to parse an LXP region for dynamic content than it is
to process a plain HTML region.
