== Overview ==
Actually, GeoNetwork ignore all gco:CharacterString substites due to the following lines in schema-substitutes.xml :
{{{
<!-- override all the schema substitutes for gco:CharacterString 
	- we don't want any--> 
	<field name="gco:CharacterString">
	</field> 
}}}
It also provide by default all substites of an element. The proposal allows to filter substitution list.


The idea of the proposal is to be able to some elements to be able to use one or more substitutes of gco:CharacterString. Indeed, some substitute like gmx:FileName or gmx:Anchor could be useful in some situation. 
The proposal add :
 * a way configure allowed substitutes for an element
 * add support for gmx:FileName to be used to store a document in the catalogue
 * suggest only gml:Polygon for bounding polygon choice list.
