I got it now. I have to start from <fieldType/> to create my <field/> list. If I want a list of supported field-types (used in my schema.xml), I have to look at the "class" attribute of <fieldType/> to get that list. The out-of-the-box list of field-types is documented in the link you provided: https://cwiki.apache.org/confluence/display/solr/Field+Types+Included+with+Solr
