/**
* Implements a FileProvider for UI purposes. Note that it might not be very
* reliable as long as we have not fixed login & multi repository issues that
* will be addressed in the next version.
*
- * We are also very dependant of the repository architecture for file nodes. We
- * assume the content of the file is stored in a nt:resource child node of the
- * nt:file in the jcr:data property
+ * NOTE: id used here is the real id of the JCR Node, not the JCR Path
+ *
+ * Relies on common approach for JCR file handling implementation.
