[x3d-public] Patched file, please review

[John Carlson]

I didn't realize that ' was acceptable.  I knew " used to be 
acceptable, and may still be. This is the first time I've see ' and 
there were complaints, but I can't recall which tool. I am also getting 
complaints about the '"Times"'.

So I reference:

https://www.web3d.org/documents/specifications/19776-3/V3.3/Part03/concepts.html#X3DCanonicalForm 
which I believe is the latest XML encoding standard (reviewing, I see 
there's a 4.0 draft).

"Double-quote and single-quote characters:

 1. Individual MFString array values are bounded by "double-quote"
    characters, each separated by a single space.
 2. The overall MFString attribute is contained within 'single-quote'
    characters.

    EXAMPLE 1 |<NavigationInfo type='"WALK" "EXAMINE" "ANY"'/>|

 3. Single-quote characters within an MFString value are replaced by the
    |′| character entity.
 4. Double-quote characters within an MFString value are replaced by the
    |"| character entity (and escaped by a leading backslash
    "\" character).
 5. XML " character references that delimit individual strings in
    an MFString array are converted to double-quote characters.

    EXAMPLE 1 |<Text string=' "\"Hello, quotation marks\""
    "Line 2 has no quotation marks" '/>| displays the following two lines:

         “Hello, quotation marks”
         Line 2 has no quotation marks"


Please read the above and tell me what I'm doing wrong.  This seems to 
indicate that newlines, tabs, etc. be are allow between SFStrings in an 
MFString in XML, but I don't know about HAnim or X3DV4.

The above also indicates that ' is not a good encoding for 
single-quote characters, although it's OK XML.


I'm not really sure where else to look for X3D Canonical Form, clicked 
the first link on Google, dang, that's 3.3. Okay, I see version="4.0" 
X3DV4 in the audio X3D files.   But X3DV4 doesn't cover XML encoding 
that I know of?  I will look through the drafts.  Okay, I see:

https://raw.githubusercontent.com/Web3DConsortium/X3D/master/ISO-IEC19776/ISO-IEC19776-3/ISO-IEC19776-3v4.0/ISO-IEC19776-3v4.0-WD1/Part03/concepts.html 
(I did try to read this).

Or:

https://raw.githubusercontent.com/Web3DConsortium/X3D/master/ISO-IEC19776/ISO-IEC19776-3/ISO-IEC19776-3v4.0/ISO-IEC19776-3v4.0-WD1/Part03/concepts.html#X3DCanonicalForm 
(not found).

I don't see any way to show this except by downloading from the github 
site. I have already seen the HTML--looks like gobbledegook, as that's 
what's shown on github.  Is there another way to view github that will 
show the rendered file?

Looking here:

https://www.web3d.org/specifications/

I do see the 3.3 XML encoding standard referenced as first link above.


I don't really want to spend time downloading the standard yet. Is there 
someplace you can privately share the rendered X3DV4 Canonical Form on 
the web for me as a member of web3d consortium? Seems like creating a 
member accessible version would be very handy for collaboration, and 
then there would be no disagreements (which version do you have, etc.).

This might be a good place on the web3d.org website to put member 
documents?  It's under "Documents" on the main web3d.org site. 
https://www.web3d.org/about/documents


I'm not sure I can share the X3D 4.0 XML encoding standard on the 
mailing list?   Should I contact you directly once I've viewed the 4.0 
version?  So far, I've just viewed it on github.  Yes, I realize I am 
not up on all the encoding standards at this time, mostly I am focused 
on getting JSON/JavaScript working.  My second priority is HAnim.  XML 
is way down the list of my priorities.

I'm a bit nervous having proprietary info on my computer right now.  A 
virus scan did not go perfectly (100 false positives), so I'm a bit 
nervous. What I'll do is download the snapshot, render and send a 
picture to Don directly, then delete my version.

Thanks!

John
