A generic Diggs 2D sampling feature that represents a surface thatdefines the sampling space. The featureExtent property can be of a PlanarSurfacegeometry (used for simple cross-sections or maps), where the surface is entirelycoplanar, or a MultiPlanarSurface geometry, where the overall surface consists ofmultiple coplanar patches (used for dog-leg sections or non-complanarsurfaces).
Database handle for the object. It is of XML type ID, so is constrained to beunique in the XML document within which it occurs. An external identifier for the object inthe form of a URI may be constructed using standard XML and XPointer methods. This is doneby concatenating the URI for the document, a fragment separator, and the value of the idattribute.
<div><h3>lang (as an attribute name)</h3><p>denotes an attribute whose value is a language code for the natural language of the content of any element; its value is inherited. This name is reserved by virtue of its definition in the XML specification.</p></div><div><h4>Notes</h4><p>Attempting to install the relevant ISO 2- and 3-letter codes as the enumerated possible values is probably never going to be a realistic possibility.</p><p>See BCP 47 at<a href="http://www.rfc-editor.org/rfc/bcp/bcp47.txt">http://www.rfc-editor.org/rfc/bcp/bcp47.txt</a>and the IANA language subtag registry at<a href="http://www.iana.org/assignments/language-subtag-registry">http://www.iana.org/assignments/language-subtag-registry</a>for further information.</p><p>The union allows for the 'un-declaration' of xml:lang with the empty string.</p></div>
