+ *
+ * TAttributeCollection implements a collection for storing attribute names and values.
+ *
+ * Besides all functionalities provided by {@link TMap}, TAttributeCollection
+ * allows you to get and set attribute values like getting and setting
+ * properties. For example, the following usages are all valid for a
+ * TAttributeCollection object:
+ * <code>
+ * $collection->Text='text';
+ * echo $collection->Text;
+ * </code>
+ * They are equivalent to the following:
+ * <code>
+ * $collection->add('Text','text');
+ * echo $collection->itemAt('Text');
+ * </code>
+ *
+ * Note, attribute names are case-insensitive. They are converted to lower-case
+ * in the collection storage.
