[Mohammed Al-Mar]

In UI Page com.glideapp.servicecatalog_cat_item_view there is a tag 'g' looks like it's used to include kind of UI

<g:catalog_item />

<j2:if test="$[jvar_cat_item_authorized]">
      <div id="cat_item_view" class="" sn-atf-blacklist="IS_SERVICE_CATALOG">
        <input type="hidden" id="log_variable_actions" name="log_variable_actions"  value="${gs.getProperty('glide.sc.log.variable_actions')}" />
        <g:catalog_item />
	   
	    <j:if test="${new GlideappScriptHelper().isUI16Enabled()}">
			<script>
				catalogHistory.setHistory('$[HTML,JS:sc_cat_item.name.getDisplayValue()]', catalogHistory.getPageUrl());
			</script>
	    </j:if>
	    </div>
   </j2:if>

I found the solution; the tags 'g' and tag 'g2' in ServiceNow UI Pages are used to include UI Macros.
