/* How finding a typename from an xmlNode works ?
|
|
*
|
|
* There is three way to get to a typename:
|
|
* 1. by an xsi:type QName attribute, that we resolve
|
|
* 2. by constructing a QName from the namespace of the xsi:type and the name of the node
|
|
* 3. by resolving the QName of the node
|
|
*
|
|
* To resolve a typename you must map the QName using the default registry object, or use
|
|
* prefix_from_href_and_nodename() to mat the QName to a prefix used to build the typename with this
|
|
* template: typename = "Lasso" + prefix + name_part(QName).
|
|
*
|
|
* The resolving algorithm is in the function _type_name_from_href_and_nodename().
|
|
*
|
|
* The prefix extraction in prefix_from_href_and_nodename().
