10.13 Requirements Class: Monitoring Point
This requirements class is to be used to describe monitoring points sampling points that are described using a point-based geometry. WaterML2.0 extends the OMXML Sampling Point type
to add metadata specific to hydrological monitoring.

The Deddington monitoring point samples the Nile river. The monitoring point is at latitude 41.814935S and longitude 147.568517W and uses the Australian height datum as a reference datum. The monitoring point is in the Australian Easten
Daylight Timezone, 11 hours ahead of UTC.

10.14 Requirements Class: Collection
This requirements class is to be used to describe collections of objects from WaterML2.0. This includes observations, sampling features, sampling feature groups and inline dictionaries.

Requirement
reqxsd-collectionvalid The content model of this element shall have a value that matches the content
model defined by wml2:Collection.
See Annex B for an example collection.
10.14.1 Use of inline dictionaries
The localDictionary element allows dictionarycode items to be encoded within the collection. This allows local references to be made to the dictionary rather than external links via xlink.
Examples of its use are provided in Annex B.
