Reviewing ISO/IEC 19776-1 clause 5.15 SFString and MFString (<a href="http://www.web3d.org/documents/specifications/19776-1/V3.3/Part01/EncodingOfFields.html#SFString">http://www.web3d.org/documents/specifications/19776-1/V3.3/Part01/EncodingOfFields.html#SFString</a>) there is no mention of white space separators. However, clause 5.1.2 Description (<a href="http://www.web3d.org/documents/specifications/19776-1/V3.3/Part01/EncodingOfFields.html#5.1.2">http://www.web3d.org/documents/specifications/19776-1/V3.3/Part01/EncodingOfFields.html#5.1.2</a>) does say that “</span>Multiple-valued fields are written as an ordered list of values enclosed in quotations and separated by whitespace.”. So whitespace seems to be required. Since SFString values have quotation marks as delimiters, the requirement for whitespace could be considered superfluous. So, implementations may, or may not, expect it. In conclusion, perhaps the first example is illegal. <span style='mso-fareast-language:EN-US'><o:p></o:p></span></p><p class=MsoNormal><span style='mso-fareast-language:EN-US'><o:p> </o:p></span></p><p class=MsoNormal><span style='mso-fareast-language:EN-US'>I’m trying to follow what you want, in each case.
