Description
The <gco:CharacterString> XML elements can sometime be replaced by <gmx:FileName> elements at marshalling time. The later contains a src attribute, which may contain an absolute path. Example from ISO 19139:
<fileName> <gmx:FileName src="../path/wkj98723.jpg">Overview</gmx:FileName> </fileName>
Likewise for <gmx:MimeFileType>:
<fileType> <gmx:MimeFileType type="image/tiff"> Graphic TIFF </gmx:MimeFileType> </fileType>
The main usage for those elements seem to be in MD_BrowseGraphic.
