Query containers (see Model of a Managed Site, http://xmlsapiens.org/spec/sapiarchitecture/sapibasedcms/modelmanagedsite/) refer to the fragments of the document displayed on the site; the content of these fragments can be modified by the CMS administrator. The containers contain the code of user data queries and related formatting. The query code is provided in the syntax of the markup language of the presentation code. For example:

<sapi:apply name="qc.title.value" type="string" />
