d.wms entry in workspace file is not well formed

[kuszinger]

Workspace file are XML files and standalone & character is bad. With strict xml parsers it raises error.

In URL parameter, & should be & or ѐ

workspace file exmaple line:

[...]
<parameter name="url">
    <value>http://irs.gis-lab.info/?layers=landsat&</value>
</parameter>
[...]

xml parser error example:

xml.parsers.expat.ExpatError: not well-formed (invalid
token)
