Sometime long ago, prior 2009, tidy cleaned ALL leading, trailing spaces
from attribute values, thus can no longer distinguish between a fully
blank value like "", and a value consisting of all spaces like " ".
So in these two tests, there is a preceeding test which tests the blank case,
and tidy reports it as blank, but will no longer report the all spaces as
all spaces, but repeats the blank case.
Have amended the accesscases.txt to reflect what tidy has output for more
than the last 6+ years...
The fix for #111 added an end tag for all StartEnd tags, when outputting
HTML5, but there should be some exceptions to this.
Added a new service, isVoidElement(node) for the void elements. Perhaps
this service could be further optimised.
With this fix introduced two new services, FindNodeById and
FindNodeWithId. The former does a total tree search for a TidyTagId.
Maybe there is a way to optimise this search...
Also change the uint badForm from an on/off to a bit field, so could be
extended to other document format errors.
This is a set of kludgy fixes for MathML attribute and entities support.
It is intended that a full HTML5 entity table be added at some time, but
at present ALL entities are accepted as written when within the math
element.
Likewise all attributes are accepted on MathML elements without any check
of their name or value, even if they match attributes outside MathML.
And in the pprinter such entities are written as is from the lexer, using
a new PPrintMathML service added, using the new mode OtherNameSpace.
It is hoped all these fixes will NOT effect tidy outside the math element.
ALL fixes in the set a clearly marked '#130 - MathML attr and entity fix!'
for easy searching, and improving if possible.
