 * A component that takes an Object (for text analysis applications, this will often be a String)
 * and creates a {@link CasData}.
 * <p>
 * An example of a <code>CasDataInitializer</code> would be a component that takes an HTML
 * document and populates a CasData with the plain (detagged) text as well as document structure
 * annotations that were inferred from the locations of certain HTML tags (paragraphs and headings,
 * for example).
 * @deprecated As of v2.0, CAS Initializers are deprecated. A component that performs an operation
 *             like HTML detagging should instead be implemented as a "multi-Sofa" annotator. See
 *             {@link org.apache.uima.examples.XmlDetagger} for an example.
