How can I make an enumeration of a complex type?
For example, I want to store the following data into a xsd enumeration called Measurings
- description
- tag
- item
item
tag fileName
each one of these attributes has an specific value and this set makes one registry in my ennumeration. But the problem is that as far as I know, it's allowed just the "value" attribute in an enumeration.

There is nothing like complex type enumeration in XML Schema. You'll need to organize it externally. See
http://schemas.opengis.net/gml/3.1.1/base/dictionary.xsd http://schemas.opengis.net/definitions/axisDirection.xml
for an implementation example.
