+/**
+ * Class used to manipulate strings in the format Windows XP uses.
+ *
+ * When examining the file properties of an image in Windows XP one
+ * can fill in title, comment, author, keyword, and subject fields.
+ * Filling those fields and pressing OK will result in the data being
+ * written into the Exif data in the image.
+ *
+ * The data is written in a non-standard format and can thus not be
+ * loaded directly --- this class is needed to translate it into
+ * normal strings.
+ *
+ * It is important that entries from this class are only created with
+ * the {@link PelTag::XP_TITLE}, {@link PelTag::XP_COMMENT}, {@link
+ * PelTag::XP_AUTHOR}, {@link PelTag::XP_KEYWORD}, and {@link
+ * PelTag::XP_SUBJECT} tags. If another tag is used the data will no
+ * longer be correctly decoded when reloaded with PEL. (The data will
+ * be loaded as an {@link PelEntryByte} entry, which isn't as useful.)
+ *
+ * This class is to be used as in
+ * <code>
+ * $title = $ifd->getEntry(PelTag::XP_TITLE);
+ * print($title->getValue());
+ * $title->setValue('My favorite cat');
+ * </code>
+ * or if no entry is present one can add a new one with
+ * <code>
+ * $title = new PelEntryWindowsString(PelTag::XP_TITLE, 'A cute dog.');
+ * $ifd->addEntry($title);
+ * </code>
