The attribute data-sap-ui-config makes it possible to provide a single attribute with the configuration information for the SAPUI5 runtime.
You can use this attribute instead of attaching individual options with individual configuration attributes to the script tag. Its content is similar to the global configuration object, but without the enclosing parenthesis: It is a comma separated list of key/value pairs.
<script id="sap-ui-bootstrap" type="text/javascript" src="resources/sap-ui-core.js" data-sap-ui-config="theme:'sap_platinum',libs:'sap.ui.commons'" > </script>
