of a sitemapindex and multiple sitemap documents. Instead it will
take a default and throw and exception if the other case is found
so that the calling code can handle it.
Default is to follow ResourceSync v1.1 which distinguishes the meanings
of the <lastmod> element (resource modified time as used for Last-Modified
header) and the newly introduced <rs:md datetime="..."> attribute (the
change time in ChangeList and similar resources). There are two parameters
to control these behaviors:
spec_version - set to either '1.0' or '1.1'. If set to '1.0' then no
datetime attribute will be written or parsed
add_lastmod - set True to add a lastmod with the same value of datetime
if no specific lastmod is specified. Applies only when spec_version
'1.1' is selected, provide compatibility with systems that do not
understand datetime but instead rely on lastmod
