Enabling Declarative Support

Declarative support needs to be enabled in the HTML document by adding an attribute to the SAPUI5 bootstrap script tag.

This is done as follows:

data-sap-ui-modules="sap.ui.core.plugin.DeclarativeSupport"

SAPUI5 then requires (loads) the plugin sap.ui.core.plugin.DeclarativeSupport. When started, the plugin parses and enhances special HTML tags in the HTML document. The complete bootstrap script tag for SAPUI5 (based on a CDN version) looks as follows:

<script id="sap-ui-bootstrap"
  type="text/javascript"
  src="resources/sap-ui-core.js"
  data-sap-ui-theme="sap_platinum"
  data-sap-ui-libs="sap.ui.commons"
  data-sap-ui-modules="sap.ui.core.plugin.DeclarativeSupport"
  >
</script>
