ohair@286 163 *
ohair@286 164 * <p>
ohair@286 165 * Whitespace handling is a tricky business. Consider the following
ohair@286 166 * schema fragment:
ohair@286 167 *
ohair@286 168 * <xmp>
ohair@286 169 * <element name="foo">
ohair@286 170 * <choice>
ohair@286 171 * <element name="bar"><empty/></element>
ohair@286 172 * <text/>
ohair@286 173 * </choice>
ohair@286 174 * </element>
ohair@286 175 * </xmp>
ohair@286 176 *
ohair@286 177 * Assume we hit the following instance:
ohair@286 178 * <xmp>
ohair@286 179 * <foo> <bar/></foo>
ohair@286 180 * </xmp>
ohair@286 181 *
ohair@286 182 * Then this first space needs to be ignored (for otherwise, we will
ohair@286 183 * end up treating this space as the match to &lt;text/> and won't
ohair@286 184 * be able to process &lt;bar>.)
ohair@286 185 *
ohair@286 186 * Now assume the following instance:
ohair@286 187 * <xmp>
ohair@286 188 * <foo/>
ohair@286 189 * </xmp>
ohair@286 190 *
ohair@286 191 * This time, we need to treat this empty string as a text, for
ohair@286 192 * otherwise we won't be able to accept this instance.
ohair@286 193 *
ohair@286 194 * <p>
ohair@286 195 * This is very difficult to solve in general, but one seemingly
ohair@286 196 * easy solution is to use the type of next event. If a text is
ohair@286 197 * followed by a start tag, it follows from the constraint on
ohair@286 198 * RELAX NG that that text must be either whitespaces or a match
ohair@286 199 * to &lt;text/>.
ohair@286 200 *
ohair@286 201 * <p>
ohair@286 202 * On the contrary, if a text is followed by a end tag, then it
ohair@286 203 * cannot be whitespace unless the content model can accept empty,
ohair@286 204 * in which case sending a text event will be harmlessly ignored
ohair@286 205 * by the NGCCHandler.
ohair@286 206 *
ohair@286 207 * <p>
ohair@286 208 * Thus this method take one parameter, which controls the
ohair@286 209 * behavior of this method.
ohair@286 210 *
ohair@286 211 * <p>
ohair@286 212 * TODO: according to the constraint of RELAX NG, if characters
ohair@286 213 * follow an end tag, then they must be either whitespaces or
ohair@286 214 * must match to &lt;text/>.
ohair@286 215 *
ohair@286 216 * @param possiblyWhitespace
ohair@286 217 * True if the buffered character can be ignorabale. False if
ohair@286 218 * it needs to be consumed.
