Subject: Change pre-installed namespace URIs - remove XLink and
X-Git-Tag: Alt-Design_pre_awt_renderer_import~225
X-Git-Url: https://source.dussan.org/?a=commitdiff_plain;h=7a1158889cf92ea5dd5415789eaabb82bb8964ec;p=xmlgraphics-fop.git

Change pre-installed namespace URIs - remove XLink and
include FOX.
Define SEQ_BITS as 18 for tracking pool usage. (This and
related seqMask and getSequence()should probably be
elsewhere.)
intern() URI string.
