[x3d-public] X3D regexes for colorRGBA, image need work; X3DJSAIL junit5 test harness in place

[Andreas Plesch]

I suppose it is necessary to look at (1.6MB of) this stylesheet:

https://sourceforge.net/p/x3d/code/27143/tree/www.web3d.org/x3d/stylesheets/CreateX3dSceneAccessInterfaceJava.xslt

to see which regexes are used for the tests and how the .matches
methods are generated ? I could not find much.

The x3d regexes are intended to use within an xml context, I believe.
Within an xml context, the regexes have an implicit start and end
anchor, see:

https://www.w3.org/TR/xmlschema11-2/#regexs

where anchors are explained.

Therefore it may be necessary to add explicit start (^) and end ($)
anchors to the start and end of each x3d regex when translating to
jsail java methods with the stylesheet as java does not have the
implicit anchoring.

It may turn out that I am not of much use with xslt and java
improvements. -Andreas
