[Plugin: XML Google Maps] xhtml validation errors

First I would like to thank the author for making this great plugin.

I have recently upgraded to WordPress 3.0 and I have also switched from the classic WordPress theme to the new Twenty Ten theme.

*problem*
Now when I check my pages for XHTML-validity using the W3 validator, it seems there are some errors that are caused by the XML Google Maps plugin:

• “The frameborder attribute on the iframe element is obsolete. Use CSS instead”
• Bad value http://chart.apis.google.com/chart?cht=lc&chls=4,0,0&chf=c,ls,90,CCCCCC,0.2,FFFFFF,0.2&chxt=x,y&chxl=0:|0 km|3.8 km|7.5 km|11.3 km|15 km|1:|800 m|1000 m|1200 m|1400 m|1600 m|1800 m&chd=s:LNRUYadhnrvxy034434542zzuplkloruvtrqspnpqomkieYTPN&chs=460×200&chco=00FF00&chtt=Elevation+Profile&chts=555555,12 for attribute src on element img: WHITESPACE in QUERY.”

*reproduction steps*
Go to the W3c validator page and validate one of my pages that is using the XML Google Maps plugin:

http://validator.w3.org/check?uri=http://blog.hendricksen.eu/2009/08/31/hiking-in-norway-jotunheimen-hardangervidda

*solution*
-The google-chart url should not contain spaces and ‘#038;’ characters (i.e. url should be properly urlencoded)
-The ‘frameborder’ should be removed

I can modify the php source myself, but I’d rather see the author fix this.
