211

212
             The result will be (foo deosn't euqal access):

					<describes>100</describes>
215

         2. <additionalMetadata>

					<describes>100</describes>
219

                     <access>.....</access>
221
             </additionalMetacata>
222
            Both 100 and 200 are referenced ids of pysical/distribtuion or software/implementation/distribution.
223
            Since we moved the access part to distribution element, we don't need to keep the info. 
224
           So the output is blank - remvoing the additionalMetadata tree.
225
         3. <additionalMetadata>
226
					<describes>300</describes>
227
					<describes>400</describes>
228
                     <access>.....</access>
229
             </additionalMetacata>
230
            300 is the referenced ids of pysical/distribtuion or software/implementation/distribution. 
231
            But 400 is not. So output will be:
232
            <additionalMetadata>
233
					<describes>400</describes>
234
                     <metadata><access>.....</access></metadata>
235
             </additionalMetacata>
236
            And we will give an warning message: 400 is a not distribution id and the eml201 document does not follow EML pratice.
237
		4. <additionalMetadata>
238
                     <access>.....</access>
239
             </additionalMetacata>
240
            Since no describes, no access tree will move. So output will be:
241
            <additionalMetadata>
242
                     <metadata><access>.....</access></metadata>
243
             </additionalMetacata>
244
            And we will give an warning message:No distribution id in addtionalMetadata/describes and the eml201 document does not follow EML pratice.
