[VuFind-Tech] fieldType vs fieldtype - why, and does it matter?

[Barnett, J. <jef...@ya...>]

While perusing schema.xml for an unrelated reason I suddenly realized that two different tags are being used to delimit fieldType definitions (i.e. with 'T" and with "t").  I know that at one time in HTML case didn't matter, but that later it did.  What is the rule for generic XML (is there one), and repeating the subject heading why is this being done in vufind and will future versions of solr continue to ignore case in XML tags?
