1999-04-13  Norman Walsh  <ndw@nwalsh.com>

	* Oldversion.sgm: Changed public identifiers from DocBook V3.0 to V3.1

1999-02-26  Norman Walsh  <ndw@nwalsh.com>

	* dblib.133: New file.

	file dblib.old was initially added on branch dsssl-as-docbook.

1999-02-22  Norman Walsh  <ndw@nwalsh.com>

	* dblib.dsl: Added dingbats for lsquo and rsquo

1999-01-21  Norman Walsh  <ndw@nwalsh.com>

	* dblib.dsl: New file.

1998-12-17  Norman Walsh  <ndw@nwalsh.com>

	* dblib.dsl: branches:  1.38.2;
	Fixed (my-debug) so that it returns its argument, not the
	message displayed.  This change was actually made in 1.30,
	although it won't turn up in the change logs until 1.31.

1998-12-04  Norman Walsh  <ndw@nwalsh.com>

	* dblib.dsl: Fixed definition of sgml-root-element.  I knew there was a
	better way!
	Added sgml-root-element? to test if a node is the root.

1998-11-25  Norman Walsh  <ndw@nwalsh.com>

	* dblib.dsl: Added component-descendant-node-list and
	component-list-descendant-node-list. These find
	descendants in a list from a given ancestor.

1998-11-19  Norman Walsh  <ndw@nwalsh.com>

	* dblib.dsl: Removed version number from %library-version% (maybe I should
	rename that).  There are just too many files with version
	numbers in them.  See VERSION in the distribution for the
	distribution version.  Each file has an RCS ID that can be
	used to track it, if necessary.

	* dblib.dsl: Added component-list-child-number

	to checkpoint another project).

1998-10-30  Norman Walsh  <ndw@nwalsh.com>

	* dblib.dsl: Version 1.20 released.

	* dblib.dsl: Protect forward slash in URLs (so // doesn't confuse some
	browsers)

1998-10-19  Norman Walsh  <ndw@nwalsh.com>

	* dblib.dsl: Again.

	* dblib.dsl: Version 1.19 is released.

	* dblib.dsl: Added (string-index).
	
	Added (parse-starttag-pi), and some helper
	functions for it.  This function parses the
	xml-declaration style PI:
	
	  <?pitarget attr="val1" attr2="val2">
