are non-digit.
* Fixes a bug that mark as invalid XMLs containing use-licenses with
https scheme or missing trailing slashes.
* Changes the funding-group validation algorithm.
* Checking for funding-statement when fn[fn-type="financial-disclosure"] is
present.

* Added SciELO PS 1.2 support.
* Added the apparent sourceline of the element raising validation errors
(stylechecker).
* Added the option *nocolors* to prevent stylechecker output from being
colorized by ANSI escape sequences.
* stylechecker now prints log messages to stdout. The option *loglevel*
should be used to define the log level. Options are: DEBUG, INFO, WARNING,
ERROR or CRITICAL.
* SciELO PS 1.2 schematron uses EXSLT querybinding.
* Better error handling while analyzing multiple XML files with stylechecker.

* Fixes a bug that causes malfunctioning on stylechecker
while expanding wildcards on windows.
* Major semantic changes at *assetsdir* options. Now it is always turned ON,
and the option is used to set the lookup basedir. By default,
the XML basedir is used.

* stylechecker CLI utility overhaul:
* The basic output is now presented as JSON structure.
* The option *assetsdir* lookups, in the given dir, for each asset referenced in
XML. The *annotated* option now writes the output to a file. The
utility now takes more than one XML a time.
* *pygments*, if installed, will be used to display pretty JSON outputs.

* Added method ``XMLValidator.lookup_assets``.
* Added property ``XMLValidator.assets``.
* Fixed minor issue that would cause //element-citation[publication-type="report"]
to be reported as invalid.
* Fixed minor issue that would erroneously identify an element-citation element
as not being child of element ref.

* Minor fix to implement changes from SciELO PS 1.1.1.
