Description Lee Worden 2012-02-10 02:34:23 UTC 
Here's a real-life example, though it may contain extraneous information:

<project-file filename="deterministic-diffusion.figure.ode-experiment.  0.png" make=yes/>

This call to an extension's tag hook can not be handled correctly by the extension, because the parser's Sanitizer collapses the two spaces in the filename into one.  Strings between double or single quotes should be preserved verbatim as much as possible.
Comment 1 Brion Vibber 2012-02-10 18:44:04 UTC 
IIRC this is behaving according to XML spec; multiple literal spaces may be consolidated.

Try explicit &#32; or &#x20; or perhaps you want &nbsp; for a non-breaking space here.



http://www.w3.org/TR/REC-xml/#AVNormalize
"If the attribute type is not CDATA, then the XML processor MUST further process the normalized attribute value by discarding any leading and trailing space (#x20) characters, and by replacing sequences of space (#x20) characters by a single space (#x20) character."
