The *.xcs XML files under officecfg/registry/schema/ (adhering to officecfg/registry/component-schema.dtd) redundantly contain some element attributes that explicitly spell out the attributes' implied default values. For example, officecfg/registry/schema/org/openoffice/Office/Common.xcs contains > <prop oor:name="Password" oor:type="xs:string" oor:localized="false"> where oor:localized="false" is the default for <prop> elements, anyway. Removing such redundant data is beneficial, as it ends up in the *.xcd files that are processed when LibreOffice starts, so whatever is not present there speeds up start up by a tiny fraction. The list of relevant attributes is: * oor:extensible="false" for <group> elements * oor:localized="false" for <prop> elements * oor:nillable="true" for <prop> elements
Hmm, I generally see explicit default values as a plus, allowing one to avoid searching elsewhere for the default values. Could the tooling be improved instead to skip the values that match parent defaults?

But the vast majority of elements across officecfg/registry/schema/ already lack those explicitly-mentioned defaults, so I don't think this is a convincing argument to not drop the remaining few occurrences. > Could the tooling be > improved instead to skip the values that match parent defaults? it presumably could, it's some XSLT code
