> On the solr-user mailing list, Nutan recently mentioned spending days trying to track
down a problem that turned out to be because he had attempted to add a {{<dynamicField
.. />}} that was outside of the {{<fields>}} block in his schema.xml -- Solr was
just silently ignoring it.
> We have made improvements in other areas of config validation by generating statup errors
when tags/attributes are found that are not expected -- but in this case i think we should
just stop expecting/requiring that the {{<fields>}} and {{<types>}} tags will
be used to group these sorts of things.  I think schema.xml parsing should just start ignoring
them and only care about finding the {{<field>}}, {{<dynamicField>}}, and {{<fieldType>}}
tags wherever they may be.
> If people want to keep using them, fine.  If people want to mix fieldTypes and fields
side by side (perhaps specify a fieldType, then list all the fields using it) fine.  I don't
see any value in forcing people to use them, but we definitely shouldn't leave things the
way they are with otherwise perfectly valid field/type declarations being silently ignored.
